decommission of virtual probes
by ripe.net＠toppas.net 07 Nov '23

07 Nov '23

Hello folks, dear Atlas team, I would like to discuss the case, where a virtual probe is decommissioned because the place where you ran it will no longer be available. For example, a VPS which you have rented somewhere, but you've decided to cancel that service. Does it make sense to create and keep a backup of the virtual probe, so that you can re-deploy it later (with another AS)? Or is it better to delete the virtual probe and create a new one? Also: is there an official way to decommission a virtual probe permanently? I felt like this could be interesting for other people too, so i decided to discuss this question publicly. BR, Simon

My bad. non-hardware probes are called "software probes" non-hardware anchors are called "virtual anchors" I mixed that up. I meant software probes. BR, Simon On 06.11.23 21:16, Ernst J.

Customs value of Atlas Probe
by Christopher Munz-Michielin 06 Nov '23

06 Nov '23

Hi All, I'm fighting a bit of a battle over the value of the ripe atlas probe for the purposes of taxation (they are insisting it's value is more then $300 CAD and over $50 in taxes is owed to import it) and in order to fight this I need to provide proof of value, however, I obviously don't have a purchase receipt to show them. Is there any form that RIPE provides which shows the value of the Atlas probes for customs/import purposes that I can include with my case? Thanks!

New measurements listing page
by Stephen Suess 24 Oct '23

24 Oct '23

Hello Atlas friends, As part of our continuing improvements to the Atlas UI, we have just pushed a major update to the measurements listing page. Among the improvements: - Cleaner, simpler interface - Improved filtering and sorting - Views are sharable with all params - Improved paging - Favourite and Hide actions - and quite a bit more You can find the new page at https://atlas.ripe.net/measurements/ or in the menu under "Measurements", and the old page will remain available for a few weeks at https://atlas.ripe.net/measurements/legacy/. Your input and feedback is highly appreciated, you can reply to this message or directly to me or in the forum at https://forum.ripe.net/t/new-ripe-atlas-measurement-listing-page/725 Thanks!

Delays in web interface

Questions with regard to the measurement status and running time
by Jerome Mao 20 Oct '23

20 Oct '23

Hi RIPE Atlas Team and Community, I would like to know more about the status of measurements - I have scheduled a one-off ping measurement which utilized 15 anchors. I polled the measurement status and results from my local desktop to the restful API through cousteau Python lib. The results were returned to me in less than a minute, but it took around 13 minutes for the measurement to transition from "ongoing" to "stopped." On the other side, the time delta between the "requested start time" and "requested stop time" on the RIPE Atlas portal is 9 minutes. My questions are: 1. Why is the measurement "ongoing" even if the results have already been made available? 2. What is the meaning of the "requested start time" and "requested stop time" on the RIPE Atlas portal? 3. Will a one-off measurement release one slot from the measurement rate limit once its result becomes available even if it’s still in "ongoing" state? Thanks! Best, Jerome

Hello, FYI HE's new "supertraceroute" exposes ATLAS traceroute functionality to the public: https://bgp.he.net/traceroute/ Other sources are (NLNOG) RING nodes and other projects. Interesting approach, not sure if I should be happy about this, but I guess HE is paying for it with Atlas credits. Lukas

New measurement form is now live (and default)
by Stephen Suess 12 Oct '23

12 Oct '23

Hello Atlas Community, We have just pushed the release version of the new measurement form (that was formerly in beta) to production. It is now the default (and lives at the same url as the old form) and the old one has been renamed legacy and will remain available for a few weeks in the menu and linked from the new form. Please check it out and let us know if you find any issues. We really appreciate the feedback given by the community during the beta, it helped us evolve and improve the form significantly. You can find the new form at https://atlas.ripe.net/measurements/form/ Thanks! Stephen RIPE Atlas UI

Changes to RIPE Atlas API keys
by Robert Kisteleki 04 Oct '23

04 Oct '23

Dear RIPE Atlas users, We'd like to update you on some upcoming changes regarding API keys in RIPE Atlas. TL;DR nothing changes regarding how you can use your API keys in the short term - as long as you're actually using them. However, we'll change how unused or forgotten keys are handled as well as remove the less secure in-URL use of them. At the moment RIPE Atlas users can query their existing API keys via the UI and API, including the possibility to retrieve old keys. In order to improve the security of how we handle these, we'll introduce the following changes in October 2023: * The listing (retrieval) of keys will only reveal parts of the keys (enough to identify them) in the API as well as in the UI. * We'll add the ability to "regenerate" an API key, which will replace the secret UUID of the key while keeping exactly the same permissions. * Unused API keys will automatically be frozen after 1 year of not being used. Active keys (i.e. the ones that have been used at least once) will not be frozen. You still have the ability to save your keys until these changes are done and, as written above, you will be able to regenerate them later. We'll notify this list when the changes are about to be done. In addition, in order to further increase the security of our system, in the long run we'll make changes about how these API keys are communicated to the API: * At the moment the API accepts these either in HTTP headers ("Authorization" header) or in the URL (?key=xyz), although the Authorization header version has been documented as the preferred version for some time. * We'll deprecate and remove the ability to use the URL form in about a year (around October 2024). * We plan to send further reminders about this change over time, as well as reaching out to heavy users of the to-be-removed format. Regards, Robert Kisteleki RIPE Atlas team

Changes to RIPE Atlas API auth status codes on 2 Oct
by Chris Amin 02 Oct '23

02 Oct '23

Dear colleagues, Currently the RIPE Atlas REST API (https://atlas.ripe.net/api/v2/) returns a 403 Forbidden status code in two cases: * When a request requires authentication but the user has not provided any credentials, or has provided incorrect credentials * When a user has authenticated correctly, but they or their API key lacks the permissions needed for a particular request Distinguishing between these two cases is important because in the first case the client can potentially get access by authenticating, and in the second case there is no point in retrying authentication with the same credentials. In order to enable this distinction, and to generally conform to web standards and best practices, on Monday, 2nd October we will change the REST API so that a completely unauthenticated request will receive a response with a 401 Unauthorized status code. The 403 Forbidden status code will still be returned for users and API keys that are authenticated but lack the necessary permissions for the request. As a temporary migration measure, the API will keep the same behaviour (always return 403) if either: * The "Referer" header contains "RIPE Atlas Tools" and a version string <= 3.1.1, or * An "X-Compat" header is set and contains the string "auth-2022" This temporary measure is guaranteed to work for the rest of 2022, after which it will be removed and the API will always make the 401/403 distinction. Kind regards, Chris Amin RIPE Atlas team

Will probes catch up?
by Ernst J. Oud 21 Sep '23

21 Sep '23

Hi, Some of my probes, all on different providers, (for instance: https://atlas.ripe.net/probes/1005104/#tab-builtins) have not catched up after the recent disruption. Will this happen automatically? They are connected, streaming results are ok., so I guess I don’t need to restart them? Regards, Ernst J. Oud

One-off measurements stopped after 5-6 minutes without results
by Gerdriaan Mulder 20 Sep '23

20 Sep '23

Hi list, A few hours ago (around 15:00Z), I launched some one-off measurements[1][2][3] on the platform for a select number of probes (based on ASN and region). The target in all three cases was 2a02:1807:1020:700::1 (no hostname, purely the address). Although the number of requested and participating probes varied a bit, it seems none of the measurements yielded any results. At the time I didn't look at recent posts on this mailing list, nor was I aware of this ongoing incident[4] on the Atlas backend. It seems like that incident might be the cause of the (current) unavailability of these results. It would be great if anyone can confirm that (viewing results of) user-defined measurements are affected as well. Aside, I suppose the following messages on "My RIPE Atlas Dashboard" are also caused by the mentioned incident[4]? --->8--- 2023-09-18 16:40 UTC Your probe #11nnn was automatically untagged as "system: Resolves AAAA Correctly" 2023-09-18 16:40 UTC Your probe #11nnn was automatically untagged as "system: Resolves A Correctly" 2023-09-18 16:20 UTC Your probe #11nnn was automatically untagged as "system: IPv6 Works" 2023-09-18 16:20 UTC Your probe #11nnn was automatically untagged as "system: IPv4 Works" ---8<--- Perhaps the incident page[4] can include a few lines of the current (estimated) impact, as well. Best regards, Gerdriaan Mulder [1] https://atlas.ripe.net/frames/measurements/60161706/ (default IPv6 traceroute) [2] https://atlas.ripe.net/frames/measurements/60162230/ (IPv6 traceroute, paris=0) [3] https://atlas.ripe.net/frames/measurements/60162753/ (default IPv6 ping) [4] https://status.ripe.net/incidents/wfd7qywz3v68

Issues with Atlas back-end
by Ernst J. Oud 19 Sep '23

19 Sep '23

Hi, From September 18th there is an issue with the Atlas back-end, already 9 hours delay. Built-ins show data until around 14:00 UTC. It is now midnight. I am confused, the status page (https://status.ripe.net/) at the bottom says: “Resolved - The backend team could restore the service level and with that issues in RIPEstat stopped as well. Sep 18, 15:11 UTC” It clearly is not resolved. On the top of that status page it says: “Investigating - We are experiencing issues with the RIPE Atlas backend and currently are investigating this issue. Sep 18, 2023 - 14:07 UTC” So what is the status? Regards, Ernst J. Oud

Probe issues - now recovered
by Nigel Metheringham 04 Sep '23

04 Sep '23

Probe Id 22680 This v3 probe started playing up a couple of months back but I had not had a chance to properly investigate until this weekend. Symptoms were that it disconnected and reconnected every minute or so - my August availability report was nearly 14K lines long! Packet trace showed that it was connecting to the RIPE atlas hosts on port 433 (but talking ssh), and after a minute or so was sent a FIN from the RIPE end. Tried a few things without success, so replaced the USB stick this morning, and so far (only a few hours in) that appears to have fixed the issue... The replaced USB stick was the original I got with the hardware something over 8 years back. Nigel.

I used WireShark on the WAN interface and I can confirm that the messages are all ping requests. Further, I can confirm that all of the addresses have been mangled. They are logged as fe80:5::, but the correct addresses are fe80::. I created a bug report. -----Original Message----- From: Michel Stam <mstam(a)ripe.net> Hi Daryl, Can't say I've seen it before, can the firewall be a bit too strict?

Recently, I noticed that there are hundreds of messages in the log of the router like the following: Aug 12 22:38:54 kernel cannot forward src fe80:5::1cce:5fff:fe02:61b6, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 22:36:06 kernel cannot forward src fe80:5::e65d:370f:fc45:b5ba, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 22:11:31 kernel cannot forward src fe80:5::3c01:20ff:fee5:f601, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 17:45:08 kernel cannot forward src fe80:5::2a0:a50f:fcdb:db7c, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 15:47:09 kernel cannot forward src fe80:5::2a0:a50f:fcb9:c28e, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 08:13:04 kernel cannot forward src fe80:5::2a0:a50f:fc8a:8134, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 06:55:33 kernel cannot forward src fe80:5::bac2:530f:fc39:164a, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 03:39:05 kernel cannot forward src fe80:5::2a0:a50f:fc8a:85c0, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 01:17:54 kernel cannot forward src fe80:5::e6fc:820f:fcea:2016, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 12 00:55:09 kernel cannot forward src fe80:5::ee9e:cd0f:fc0d:79d4, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 11 15:47:11 kernel cannot forward src fe80:5::4271:830f:fce5:7fa, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 11 15:25:42 kernel cannot forward src fe80:5::bac2:530f:fcd4:fdd2, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 11 07:33:53 kernel cannot forward src fe80:5::cd08:c204:cc63:2d32, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 11 06:17:19 kernel cannot forward src fe80:5::fe33:420f:fcdc:5932, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 11 04:49:00 kernel cannot forward src fe80:5::7e25:860f:fc44:6742, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 22:41:25 kernel cannot forward src fe80:5::9ca0:15ff:fe87:842e, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 14:38:59 kernel cannot forward src fe80:5::c80a:daff:fe92:b8b7, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 10:55:07 kernel cannot forward src fe80:5::2a0:a50f:fc8a:6ea0, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 08:57:19 kernel cannot forward src fe80:5::46aa:500f:fceb:ad66, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 05:47:09 kernel cannot forward src fe80:5::b68a:5f0f:fcb2:1040, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 03:24:58 kernel cannot forward src fe80:5::2a0:a50f:fcb6:5ea2, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 03:08:55 kernel cannot forward src fe80:5::2a0:a50f:fc90:9d4, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 00:17:07 kernel cannot forward src fe80:5::e65d:370f:fc44:15ba, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 Aug 10 00:07:07 kernel cannot forward src fe80:5::2a0:a50f:fcb7:7c, dst 2001:569:585f:b00:1:b3ff:fedd:9f24, nxt 58, rcvif hn0, outif hn1 The messages occur in groups of three, spaced a few seconds apart. All of the messages start with fe80:5. Even if I strip off the "5", none of them seem to convert into MAC addresses, so I can't use that to figure out what type of device is pinging the probe. There are no entries in the NDP table corresponding to these messages. I have no idea how long this has been happening. I only noticed it when I was setting up a new server to host pfsense. My probe is RIPE-Atlas-Probe-52209. I'm interested to know if anyone else has experienced this.

Probe with ever changing upstreams/ASs?
by Carsten Schiefner 04 Aug '23

04 Aug '23

All - I wonder whether this is a good idea or rather a really bad one... I have a free port on a Freifunk router where I could plug in a RIPE Atlas probe. Freifunk is a community where you - amongst other things - can offer a bit of your bandwidth to "the world". This connectivity sharing however is set up as a tunnel to various ISPs (for-profit companies and non-profit associations) as these would enjoy the "provider privilege": that in short is not to be held accountable for e.g. copy right infringements etc. ("Störerhaftung"). Anyhow: as part of this tunnel setup, the other end of the tunnel changes every 24 to 48 hours - and so does the upstream and therefore also the AS of the upstream provider. And now I am asking myself: a probe with ever changing upstreams/ASs - shall such an addition to the RIPE Atlas network be considered a fault or a feature? Any comments, anybody? Cheers, -C.

System tag
by Ernst J. Oud 04 Aug '23

04 Aug '23

I noticed that the system tag “IPv4 stable 1d” is gone from my probe at: https://atlas.ripe.net/probes/1005104/ I use that tag as a criteria to select active orobes for measurements. But I noticed that my own probe was not included in my measurements. Which is weird since my probe has been online for 2.5 days (normally it is more stable, but my ISP had a small downtime). So my question is what triggers this tag? The tag is self explanatory but what does “stable” mean? Regards, Ernst J. Oud

Hi! It depends on use case. For me, such probe would be fine for one-off measurements but for continuous measurements I would filter out such probe to avoid noise in data. However, when I looked on freifunk.net map I noticed that this network span across Germany, Switzerland, and Austria so even for one-off measurements usage of such probe is questionable because I never know where remote end of the tunnel is. If I understand correctly it can jump from country to country every day. In other words, such probe would be tricky to handle and user will have to be aware how such probe behave to properly handle data generated by it. Probably new system tag would be needed to mark such exotic probe.

Easy way to view DNS results?
by Micha Bailey 27 Jul '23

27 Jul '23

Hi, I’m wondering if I’m missing something - I ran a DNS measurement with 110 probes, and the results are in, but the site UI seems to only show the result status and time elapsed until response, but not the results themselves. Looking at the JSON from the result endpoint I’m seeing that it seems to return the raw binary response - is there a particular reason it can’t be parsed and displayed in a more human-readable format? I know there are libraries and tools that do result parsing, but being on mobile at the moment (and often) means those are somewhat less accessible as far as I’m aware.

Re: [atlas] DoH and DoT measurements
by Ponikierski, Grzegorz 26 Jul '23

26 Jul '23

Indeed “tls” flag seems to work. Thanks! After first try with DoT providers like one.one.one.one or dns.google I have additional question. When exactly FQDN from “target” is resolved to IP? Is RIPE Atlas resolve domain to IP only once during measurements creation or is each probe resolve domain to IP individually? It’s important details for me because I will work with FQDN that will resolve do different IP depending on user location so if it is resolved only once by RIPE Atlas system then probes will be using sub-optimal IPs to run tests.

Issues downloading large result files
by Ana 21 Jul '23

21 Jul '23

Hi everyone, I'm seeing something very strange when trying to download the result files for some large measurements. The download is a different size each time (sometimes 1.4GB, then 3.2GB, then back to 1 GB again) and checking the end of the file I can always see it's not complete as it stops in the middle of a measurement, closing brackets aren't there etc. I guess this is because of the size of the file, not sure if there's some sort of limit on RIPE Atlas? If anyone here has seen anything like this or has any advice on how to fully download the result that would be much appreciated! Thank you, Ana

Magellan
by Ernst J. Oud 26 Jun '23

26 Jun '23

Hi, Perhaps someone can help me. I use Magellan to create a measurement using connected probes on AS15435. First I search for probes using Magellan and then I supply the ID’s returned of those probes reported as “connected” when creating the measurement. I don’t want to wait for the stream to time-out so I use the “stream-limit” parameter, equal to the number of supplied connected probes. So when that number of connected probes have supplied data the streaming is complete. However, it appears that probes are reported as connected by Magellan but do not supply data when specified for a measurement, for instance probe 2565. That probe is Reported by Magellan as connected but when I use it in a measurement it does not supply data. Thus streaming will only time-out and does not stop not when spevified connected probes have supplied data. Apparantly “connected” does not imply “can be used in a measurement”. How can I supply probe ID’s in a “create measurement” command using Magellan knowing for sure that these probes will supply data? Regards, Ernst J. Oud

It is down for 10-ish hours a weekday. It's been running like this for months now. Suddenly, I've just got this mail below about my probe. The probe is online every day and was online today as well.

Fw: Action Required: RIPE Atlas Probe 52974 and RIPE NCC Days Sofia invitation
by Endre Szabo 20 Jun '23

Hi folks, I've got a probe running at a very remote site. Since the energy prices were skyrocketing with the crisis here in Eastern Europe, the probe does not have 7x24 power anymore. It is down for 10-ish hours a weekday. It's been running like this for months now. Suddenly, I've just got this mail below about my probe. The probe is online every day and was online today as well. Does this mail mean that RIPE is unsatisfied with my uptime, and I must return the probe? Or is it some monitoring needing some tuning? --Endre ----- Forwarded message from RIPE Atlas <no-reply(a)ripe.net> ----- From: RIPE Atlas <no-reply(a)ripe.net> Subject: Action Required: RIPE Atlas Probe 52974 and RIPE NCC Days Sofia invitation Date: Tue, 20 Jun 2023 13:01:05 -0000 Dear Endre Szabo, We hope this email finds you well. We noticed that your probe with ID 52974 has been disconnected for some time now, and you have probably received reminders from our system asking you to reconnect it. We would like to request you to please either reconnect the probe, or if that is not possible, to return it to us to be refurbished. There is a long waiting list of people keen to receive new probes, and because of global component shortages, we have a very limited number available. 1. You can check your probe using this link below. https://atlas.ripe.net/probes/52974/#tab-status If your probe is already online, you can stop reading here! 2.
