Credits for an assignment
by Stuhrberg, Florian 03 Feb '25

03 Feb '25

Dear all, I hope you are doing well. My name is Florian Stuhrberg, and I am a master's student at Hasso-Plattner-Institut in Germany. As part of an assignment, I am currently investigating in DNS over UDP and DNS over TLS response times, using the RIPE Atlas and the corresponding API. However, after my measurements for DNS over UDP, I do not have sufficient credits to conduct the measurements for DNS over TLS. Is it possible that you could kindly share some RIPE Atlas credits, so that I can finish the assignment? Please feel free to let me know if you need any more information. Thank you in advance. Kind regards, Florian Stuhrberg

Why measurements using api are apt to fail while those using web interface can usually succeed?
by 孙乐童 02 Feb '25

02 Feb '25

Dear all, I have been attempting to use Atlas to launch traceroute measurements recently. Initially, I used ripe.atlas.cousteau to run the measurements in batches, keeping the total number under 10,000 to avoid exceeding the measurement limit. However, only 10% of the measurements returned successful results, while the other 90% showed the status "scheduling denied." Next, I tried launching only 12 measurements in batch, where each measurement contained one traceroute from a specific probe to a designated IPv4 destination. Out of these, 4 succeeded and the other 8 showed the status "specified". Following that, I launched the 12 measurements one by one with 2-second intervals, resulting in a success rate of 6 out of 12. However, when I increased the interval to 3 seconds, the success rate dropped to 4 out of 12. Interestingly, when I created the same measurements for the designated probes and destinations through the web interface, all of them were successful. Below is the Python code I used to launch the measurements: fromripe.atlas.cousteauimport ( Traceroute, AtlasSource, AtlasRequest, AtlasCreateRequest, AtlasResultsRequest, AtlasLatestRequest, ProbeRequest ) traceroute=Traceroute(af=4, target=dstip, description="traceroute subpref ip {} from {}{}".format(dstip, probe_type, probe_value), protocol='ICMP') if probe_type =='asn': probe_value =int(probe_value) source = AtlasSource(type=probe_type, value=probe_value, requested=1, tags={"include": ["system-ipv4-capable"]}) _key = ATLAS_API_KEY_2 for _ inrange(2): atlas_request = AtlasCreateRequest( start_time=datetime.utcnow() + timedelta(random.randint(0, 1)), key=_key, measurements=[traceroute], sources=[source], is_oneoff=True ) (is_success, response) = atlas_request.create() if is_success: print('create_task', dstip, is_success, response) msm_id = response['measurements'][0] return Could you kindly let me know if there might be an issue with my approach or provide any advice on how to improve this process? I would greatly appreciate any guidance. Thank you very much! Best regards, Sun Letong

Ripe Atlas Measurement Results and API Usage
by Huseyn Gambarov 30 Jan '25

30 Jan '25

Hello. I was implementing a mechanism to read the measurement results from the Ripe Atlas for many asynchronous measurements. In this process, I have faced multiple questions regarding the internal mechanisms of Ripe Atlas, and I would be thankful if you could help me clarify them. First, in the Ripe Atlas, I sometimes get “-1” in the result indicating 100% packet loss and sometimes very long RTTs. Can you tell me please what is the condition when Ripe gives up on a target and marks it as "-1”? Second, I have implemented asynchronous reading using web sockets and faced a rate limit on several concurrent web socket connections. The error message said: 'There are too many connections from this IP address. Try making multiple subscriptions on the same connection.’ Can you tell me please, if there is a limit on the number of subscriptions on the same connection? To solve the issue in the second question, I implemented a polling mechanism that periodically checks if the measurement is finished. In order to not overload the API, I attempted to retrieve multiple measurement results in a single call using the following API endpoint: GET /api/v2/measurements/{pk}/latest/ The documentation of that API endpoint states: "Get the most recent results from one or more measurements”. However, I need help understanding how to specify multiple measurement IDs in this endpoint, because all options I tried failed with HTTP status code 405 (Method Not Allowed). Could you please show me the correct way of using this API endpoint? Thank you! With regards, Huseyn Gambarov

Oddity in "atlas-probe-traffic" measurement data/graph
by ripe＠nurfuerspam.de 28 Jan '25

28 Jan '25

Hi, Probes report the traffic volume they see on the device's/machine's interfaces in built-in measurement #9002 (on software probes, this needs to be enabled manually for privacy reasons). I use that to keep an eye on the behavior/health of the probe's host machine via the graphs generated by RIPEstat, which works well most of the time. Sometimes, however, there is an oddity in the data, namely extreme outliers. See attached graph, showing a peak of greater than 6.6 Gbps, when the "normal" traffic rarely exceeds 2Mbit/s. The underlying data shows an unusual high amount of bytes/packets sent/received for one instant that is pretty much impossible, here the data points around the anomaly (from [1]): [...] { "timestamp": 1736330734, "bytes_recv": 70881.58333333333, "bytes_sent": 63566.92222222222, "packets_recv": 737.8166666666667, "packets_sent": 700.6, "interfaces": [ "eth0" ] }, { "timestamp": 1736330921, "bytes_recv": 925866981.9732621, "bytes_sent": 820879052.6524065, "packets_recv": 8351935.347593583, "packets_sent": 8177239.866310161, "interfaces": [ "eth0" ] }, { "timestamp": 1736331101, "bytes_recv": 106008.85555555555, "bytes_sent": 88055.43333333333, "packets_recv": 1100.5944444444444, "packets_sent": 971.6666666666666, "interfaces": [ "eth0", "he-ipv6" ] }, [...] I think I've seen similar behavior on all of my software probes at one time or another, don't recall whether this also previously occured with my HW probe. So far, I have not been able to manually reproduce this, but it seems this is typically related to issues in communication with the controller, be it something on the controller side, like was more frequent/pronounced during the migration to the new controller infrastructure. Be it something on the probe side, e.g., temporary issue in network stack configuration. My current hypothesis is that when the probe cannot send off the measurement data, the accumulated data _for this particular measurement type_ is somehow getting corrupted, and the corrupted data is then sent once the communication issues are resolved, and data upload resumes. E.g., in this case, from the logs, it looks as if a reregistration with the controller was being done during minute 10:08, with the measurement data for #9002 taken just when the re-registration started. Not sure whether that is just coincidence, or whether there is a causal relation between the two. Anyone else seeing something similar, occasionally at least? Any idea what might be going on? (Have not gotten too far yet scouring through the probe/measurement code to see whether that yields any hints.) Thanks! R.

Small upcoming change in measurement metadata daily dumps
by Robert Kisteleki 28 Jan '25

28 Jan '25

Hello, We plan to make a small change in the measurement metadata daily dumps available at https://ftp.ripe.net/ripe/atlas/measurements/. Up until now these files contain the "current working set" which is defined as any measurement that runs right now or has been running in the past 14 days. (This also means that there's considerable overlap between today's and yesterday's dump.) We'll shorten this period to 7 days in early February. This has zero effect on the vast majority of our users. Those who periodically download and use these files with lower than 7 day frequency will need to update their scripts accordingly. Regards, Robert Kisteleki for RIPE Atlas team

Hi, I just noticed my probe (1008458) shows a strange status: System Resolves A or AAAA Records Incorrectly But looking at the tags I see both the resolves correctly and the resolves incorrectly tags are set for both A and AAAA. That looks like a strange combination of tags. Any idea what’s causing this ? Cheers, Paul

Requested and participating probes
by Huseyn Gambarov 13 Dec '24

13 Dec '24

Hello. I am currently working on a project that heavily relies on Ripe Atlas Ping measurements. During the development, I noticed that sometimes when, let’s say, I request 3 probes, only 2 are participating in the measurement. In the Ripe Archive, I found that there was a similar discussion here - https://mailman.ripe.net/archives/list/ripe-atlas@ripe.net/thread/D6QZS4WC5… I have two questions, that I could not find answers to, and I would be very grateful if you could help me with them. First, in the mentioned discussion it is said that there are multiple reasons why fewer probes are participating and there is ongoing work to allow users to obtain information about specific conditions that occurred during the measurement creation. Can you tell, if there is a way to get that information via API? Second, do you know if there is a reasonable timeout to wait before a new attempt to reschedule the probe that failed to participate in the first measurement? Thank you for your help. With regards, Huseyn Gambarov.

Understanding how to use the `paris` parameter
by Bhaskar, Abhishek Vasisht 13 Dec '24

13 Dec '24

Hello y'all! I'm a PhD student from Georgia Tech and had a question about the "paris" field when performing traceroute measurements. The RIPE documents states that ```Paris - A number greater than 0 will indicate the number of variations to be used for a Paris traceroute. Setting the value to 0 makes the measurement use the standard traceroute``` But regardless of what Paris value I give to the traceroute measurement, I only get one path with a single paris_id. I would expect that if I gave a paris value of 10, I should see 10 potential variations of the path between A and B, correct? Please correct me if I'm wrong. Here is an example measurement https://atlas.ripe.net/measurements/84562046 Thanks! -- Abhishek Vasisht Bhaskar Student, PhD in Computer Science Georgia Institute of Technology https://abhishekvasishtb.github.io/

Streaming result data missing probe information with "enrichProbes: true"
by Wouter de Vries 27 Nov '24

27 Nov '24

Hi folks, When using the Streaming API there is an option called "enrichProbes" which should cause probe metadata to be added to every result. That seems to have worked for a while, but it has stopped working. Example code (in python) to reproduce (it's the example from the docs, with just enrichProbes set to true): import json import websocket ws = websocket.WebSocket() ws.connect("wss://atlas-stream.ripe.net/stream/") params = {"streamType": "result", "msm": 1001, "enrichProbes": True} ws.send(json.dumps(["atlas_subscribe", params])) for data in ws: print(data) Example result: ["atlas_result",{"fw":5080,"mver":"2.6.2","lts":66,"dst_name":"193.0.14.129","af":4,"dst_addr":"193.0.14.129","src_addr":"192.168.1.20","proto":"ICMP","ttl":56,"size":32,"result":[{"rtt":21.447667},{"rtt":21.226292},{"rtt":21.253375}],"dup":0,"rcvd":3,"sent":3,"min":21.226292,"max":21.447667,"avg":21.3091113333,"msm_id":1001,"prb_id":50274,"timestamp":1731917452,"msm_name":"Ping","from":"85.107.81.62","type":"ping","step":240}] As you can see there is no probe metadata present. I'm fairly sure I'm doing this right and I think this worked previously. Is something broken in the backend? Best regards, Wouter

UI feature wish: "Daily Credits Balance" pie chart widget
by ripe＠nurfuerspam.de 26 Nov '24

26 Nov '24

Hi, I very much like/liked the "Daily Credits Balance" pie chart widget from the old UI dashboard (https://atlas.ripe.net/my/). It gives an instant overview of the credit revenue and expenditure stream, not only the grand total, but also the _share_ of individual probes and measurements in the revenue and expenditure streams. With the actual number being shown when hovering over an individual slice of the pie. And clicking on a slice would take one to the page of the respective probe or measurement (though it seems currently broken for measurements, possibly because of the ongoing restructuring). Is there a way to get it back in the new dashboard, refreshed obviously, and integrated into the new overall site layout? Thanks! Kind regards, R.

Feature idea: new status "Probe (temporarily) closed for new UDMs"
by ripe＠nurfuerspam.de 20 Nov '24

20 Nov '24

Hi, Obviously, measurements are the purpose of being of the RIPE Atlas system. Thus, e.g., I take greate care to maximize probe uptime so measurements scheduled on them don't get disrupted by local events that are likely not representative of what most measurements are looking at. However, sometimes, temporary disruption may be known to come up, but is unavoidable, e.g., for maintenance of, or around the probe. Or a probe needs to be taken out of service "for good". In those cases, it is obviously hardly possible to avoid long-running measurements from being impacted, either by a short-term disruption, or by the removal of a probe altogether. And measurement owners obviously are aware of that, and need to take that into account in a way specific to each measurement's purpose. And it is obviously possible to remove, e.g., defunct probes from a running measurement and replace them with new ones. However, when a probe host knows _ahead of time_ that their probe will experience some event potentially disrupting measurements (like during planned maintenance activities), or will have to be decommissioned at a specific time in the future, how about if they could signal that condition to the Atlas infrastructure, and the infrastructure would at least not schedule _new_ measurements on such probes? E.g., by having a new probe "status" that can be explicitly set by the probe host to say, "this probe shall (perhaps just temporarily) not get any _new_ UDMs scheduled at this time (while the status is set)". Just a thought, not sure how much effort that would be to implement, and whether that would be worth the benefit of disrupting "fewer" measurements in case of foreseeable issues with a probe (or anchor), especially also upon an upcoming need to decommission one entirely. Thanks! Kind regards, R.

Re: [opensource-wg] RV: [ripe-list] Update on the Community Projects Fund 2024
by Rodolfo García Peñas (kix) 18 Nov '24

18 Nov '24

Hello, I would like to congratulate all the projects selected by the Community Projects Fund. I also wish to express my gratitude to the organising committee for initially selecting our project, 'RIPE Atlas distributed network telescope'. I am currently engaged in doctoral research on IBR traffic, and together with my supervisory team, we have proposed this project. We saw this as an ideal opportunity for the community to collect IBR traffic and make it available. We currently have a small working network of sensors (HoDiNT, Home Distributed Network Telescope [1]) and our objective is to extend the network and have RIPE manage the traffic collected. The HoDiNT sensors receive IBR traffic forwarded from the home connection router and forward it to a collector for analysis. They are fully compatible with Atlas sensors. This would enrich the traffic of other research centres, such as CAIDA or Merrit, and offer other students and research centres the possibility of having IBR traffic available for analysis. I was delighted that our project was selected, but a few hours later the organisation sent us an email stating that the RIPE Atlas team had raised some concerns about our proposal which may impact our ability to receive funding. We were requested to attend a meeting with the organisation and the RIPE Atlas team to discuss the proposal a few days later. The meeting was unfortunately not attended by a representative of RIPE Atlas. We were informed that the project was not deemed feasible. I would like to thank Alastair, who had to pass on the news to us, which is not an easy situation. I accept the decision taken, although I do not agree with either the substance or the form. I think we should have been given the opportunity to reformulate the project, maintaining the original objective but circumventing the limitations exposed. We will continue to improve HoDiNT in order to make it available to the community as soon as possible. If anyone is interested in contributing to the project, improving the code (mainly Python) and/or hosting sensors, please contact us. Due to limited resources, it is not possible to add sensors to the network openly, and we are doing so with sensors from colleagues and friends whom we thank for their time and resources.

15 Nov '24

Hi all, See the message below from Alastair from NCC. Does anyone know if the project can re-apply for the next round of funding? Kind regards, -Michael ---------- Forwarded message --------- From: Alastair Strachan <projectsfund(a)ripe.net> Date: Fri, Nov 15, 2024 at 8:48 AM Subject: [ripe-list] Update on the Community Projects Fund 2024 To: <ripe-list(a)ripe.net> Dear all, After the announcement of this year’s Community Projects Fund recipients, some challenges emerged with the RIPE Atlas distributed network telescope project which would have prevented the project from achieving the goals outlined in the project plan. After careful consideration, the Selection Committee made the difficult decision to withdraw funding for the project. While we understand this is really disappointing for the recipients, we sincerely hope they will continue initiatives that bring value to our community and the Internet. The Selection Committee has now chosen another project to support from our pool of finalists: OpenPenny - An open-source tool to identify non-spoofed traffic.

Probe disconnected, will not register. Registration servers down?
by Ernst J. Oud 13 Nov '24

13 Nov '24

My software probe 1009171 disconnected yesterday, precisely when my WAN IP address changed. Since then it tries to register but fails. So I restored it from a backup with the same result. What it tries to do, over and over again already for 9 hours, is: —- /var/atlas-probe/status/reginit.vol does not exist try new reg Ping failed start reg ATLAS registration starting there is WAIT, REG_WAIT_UNTIL , now is 1731484426 REG_WAIT_UNTIL expired go re-reg 1731484366 now 1731484426 REGHOSTS reg03.atlas.ripe.net 193.0.19.246 2001:67c:2e8:11::c100:13f6 reg04.atlas.ripe.net 193.0.19.247 2001:67c:2e8:11::c100:13f7 ssh -p 443 atlas(a)reg04.atlas.ripe.net INIT reg server asked us to wait or there was an error.

Is this a problem on my end or are the registration servers down? Regards, Ernst J. Oud

probes getting free "stress test" by postal system
by Sulev-Madis Silber 13 Nov '24

13 Nov '24

i think we need more fun here. actually it's serious too i received my v1/v2 in post in just envelope with corner open my v3 came from our vesna herself (by hands) now, v5, came in huge box with just paper sheet and probe in it. the one corner was smashed in. and poor device had been flapping around, naked, in that box, so, that introduction leaflet developed several holes in it from sharp corners of probe enclosure sure, it's free, hence maybe it's unfair but maybe they need more love. unsure who even packs them. i would guess there could be *some* padding available to stuff there? from yt comments on probe introduction video i learned that they sometimes are questionable quality too. mass produced cheap? mine survived all this abuse and i attributed the flimsily glued box to what i learned from elsewhere, that it's a budget stuff but unsure what to think...

Anomaly in NTP measurement data
by ripe＠nurfuerspam.de 13 Nov '24

13 Nov '24

Hi, In the data to date of an NTP measurement (#80845985), I find a single strange outlier with respect to the RTT value calculated: { "fw": 5090, "mver": "2.6.4", "lts": 281, "dst_name": "time2.cloud.tencent.com", "ttr": 0.413039, "dst_addr": "119.28.229.79", "src_addr": "45.11.104.146", "proto": "UDP", "af": 4, "li": "no", "version": 4, "mode": "server", "stratum": 2, "poll": 8, "precision": 1.19209E-7, "root-delay": 0.0000915527, "root-dispersion": 0.0249329, "ref-id": "647a24c4", "ref-ts": 3939345482.4404373, "result": [ { "origin-ts": 3939346062.989854, "receive-ts": 3939346062.999974, "transmit-ts": 3939346063.0000167, "final-ts": 3939346062.995442, "rtt": 4294967296.005545, "offset": -0.007347 } ], "msm_id": 80845985, "prb_id": 7030, "timestamp": 1730357262, "msm_name": "Ntp", "from": "45.11.104.146", "type": "ntp", "group_id": 80845985, "stored_timestamp": 1730357293 }, When I do the math by hand, the "rtt" value I get is 0.0055453, nicely matching the fractional part found in the measurement data. Does anyone have an explanation as to where the weird integer part might come from? Some overflow/underflow or other issue with decimal math on a binary machine? (I am not sufficiently versed in computer science to fully understand that topic, just that there are challenges in that area.) Thanks! Kind regards, R.

Fwd: RIPE Atlas Virtual Anchor Registration for DCS1 (sg-sin-as37989)
by Sanjeev Gupta 30 Oct '24

30 Oct '24

Good morning, https://atlas.ripe.net/probes/7247 I had setup an anchor last year, on a VM. I realised today while cleaning up my Atlas account, that the anchor was shown as "Down". From what I can figure out, the VM was unregistered/deleted 6 months ago. Should I apply for a new Anchor, or can I re-install and re-register (I assume the ISO will be Atlas-specific).

Your FQDN is: sg-sin-as37989.anchors.atlas.ripe.net You will need now to setup the Virtual Machine according to these instructions: (https://atlas.ripe.net/docs/anchor-installation-vm/). It is important that once you have setup the virtual machine, you log in to your RIPE Atlas account, go to the "My Atlas" menu and then "Anchors", and check the boxes “Software is installed” and "Anchor is connected to the network" so we are notified and can begin the tests. Please note that your anchor will not be fully activated until we have finished these internal tests. We will notify you once we have finished testing and your virtual anchor is ready to use. If you have any questions, please do not hesitate to contact us at atlas(a)ripe.net You registered the following details: IPv4 address: 203.123.48.20 IPv4 ASN: 37989 IPv6 address: 2405:fc00::20 IPv6 ASN: 37989 Kind regards, RIPE Atlas Team

Request for Atlas Credits
by Felix Hoffmann 29 Oct '24

29 Oct '24

Hello All, I am Felix, a Master student at the University of Potsdam (Hasso-Plattner-Institut). I am working on a measurement research project that requires longitudinal data to validate censorship (at least that is what I want to try). For that, I would like to perform measurements like Ping, DNS, and HTTP. As it's just the start of the project, I can not yet estimate how many credits I need. For the beginning, it would be great to get some and then go from there. Therefore, I am reaching out for help. I would appreciate it if some of you could offer me some RIPE Atlas credits.

Re-activated SW probe: How to get rid of red banner?
by ripe＠nurfuerspam.de 27 Oct '24

27 Oct '24

Hi I successfully reactivated and reconnected my software probe #1005585 that I had officially written off a few weeks ago. Now, how do I get rid of the red banner at the top of the probe management page reading "Note: this probe is most likely not operational, and as such it has been written off [...]"? Thanks!

Wrong IPv6 detected for my probe
by Matteo Bonora 23 Oct '24

23 Oct '24

Hello everyone, maybe it's me that I have an unusual configuration, but I was wondering if any of you are experiencing the same behavior... For IPv6 I use in my local network an ULA prefix, to maintain an abstraction layer between my network and the IPv6 prefixes assigned by my ISPs. Each ULA address of any of my devices gets translated via NPTv6 by my router to a global address compatible with my ISP assigned prefix. My probe as well has an ULA address and a public/global address that gets correctly detected by Atlas servers via IP Echo Service, but is the wrong IP that gets elected as the reference address within the Probe Address Discovery section. The correct one should come from IP Echo Service, but the ULA seems to be the preferred one. [image: 2024-10-23_00h07_14.png] Any ideas? Is there a way to force the selection of the IP Echo one? Thanks Matteo

there has been some updates iirc but same issue remains got my busted v1/v2 -> v5 shipped and went to preconfigure it at dashboard, in phone, on android firefox, it's extremely hard to scroll dashboard without it dragging all the elements all over place it's also hard to open and close them, keep clicking 10 times around the open/close element and finally got it to react could maybe someone verify it, and fix maybe. perhaps lock it down somewhere? you must use some touch device for this as issue is in hold and drag really annoying each (rare) time i go there

Re: Change git to repository (Randy Bush)
by ripe＠nurfuerspam.de 14 Oct '24

> and how does one "using the UI to replace the key?" On your probe's management page (e.g., https://atlas.ripe.net/ probes/1000006/), at the bottom of the page under the "General" tab, there is the option to add a new key. On a 5080 software probe, unless paths were changed during the build, one should find the public ssh key under /var/atlas-probe/etc/probe_key.pub (at least that's where it is on my Debian 12 system).

Software Probe version 5100
by Michel Stam 07 Oct '24

07 Oct '24

Dear colleagues, We’d like to inform you that a new version of the software probe has been released, version 5100. Please find the changes below: All platforms As of this version, the ripe-atlas-probe-measurements repository on GitHub is deprecated. Its code has been merged into the ripe-atlas-software-probe repository Package can now be built with arbitrary shell shebangs. Note that only OpenWRT ash and bash are officially supported Bug fixed where permissions are wrong when systemd is disabled (reported by César de Tassis Filho <ctassisf(a)gmail.com>) A new code signing key has been introduced. It only signs Debian packages currently, but will sign the RHEL packages in an upcoming release as well. The current RHEL key will then be deprecated. This release already supports code signed using the new key Software probes Streamlined deployment on RHEL CI/CD systemd unit ownership moved to probe and anchor packages Debian 11/12 x86_64 support added Support for OpenWRT software probes and the hardware probes v3, 4 and 5 will be added in a future release. If you run RHEL or Debian, we encourage you to upgrade to the latest version: https://github.com/RIPE-NCC/ripe-atlas-probe-doc/blob/master/manuals/Linux-… https://github.com/RIPE-NCC/ripe-atlas-probe-doc/blob/master/manuals/RHEL8-… https://github.com/RIPE-NCC/ripe-atlas-probe-doc/blob/master/manuals/RHEL9-… https://github.com/RIPE-NCC/ripe-atlas-probe-doc/blob/master/manuals/Debian… https://github.com/RIPE-NCC/ripe-atlas-probe-doc/blob/master/manuals/Debian… Best regards, Michel Stam, RIPE Atlas development team

They don’t produce data since October 1st it seems. Will the new controllers be included as built-ins? Regards, Ernst J. Oud Met vriendelijke groet, Ernst J. Oud

About the recent connection problems
by Robert Kisteleki 02 Oct '24

02 Oct '24

Dear colleagues, As many of you have noticed, we have been experiencing some technical issues with RIPE Atlas over the past few weeks. I would like to explain some of these in this email. Earlier this year, we began the process of migrating our infrastructure from our on-premise and co-located data centres to a cloud-based solution. Significant work has gone into rewriting code for multiple components and to renew the underlying infrastructure, to containerise and adapt it for the new cloud environment. In the process of this, we have encountered unforeseen bugs and bottlenecks. The RIPE Atlas team has been working to fix these issues as we find them. We are largely done with the migration of the controlling infrastructure so we hope to have a more stable system in the coming days. We are deploying new code and fixes fairly often to prevent these issues from arising, but it is possible that you might experience unexpected disconnects, but hopefully on a smaller scale than the past weeks. In the coming weeks, we will also begin the migration of the website (the user interface and the API). To clarify some questions that we heard on the list: - We will be looking for a solution to compensate credits for the missing connection times. - In the vast majority of cases, we don’t expect data loss when probes are not connected. The measurement results are delayed until the probes can reconnect and submit the results. - We apologise for the many connection and disconnection emails you might have received when your probe is disconnected. Please note that you can change your email notification preferences on your probe status page. I understand that many of you will want a more detailed explanation. We will be publishing an article on RIPE Labs, and we plan to present our work at the MAT Working Group session at RIPE 89. Regards, Robert Kisteleki RIPE NCC
