New on RIPE Labs: Announcing Daily RIPE Atlas Data Archives
by Mirjam Kuehne 02 Mar '18

02 Mar '18

Dear colleagues, In this article we present a new way to access the dataset on the RIPE Atlas platform. Instead of fetching individual results from measurements using the available APIs, you can now download files containing public measurements for a given day. Please find more details on RIPE Labs: https://labs.ripe.net/Members/petros_gigis/announcing-daily-ripe-atlas-data… Kind regards, Mirjam Kühne RIPE NCC

Plan to Implement RIPE Atlas WiFi Measurements
by Robert Kisteleki 09 Oct '17

09 Oct '17

Dear colleagues, We wanted to update the community and let you know that we plan to start work on the proposed experiment with WiFi measurements in mid-2016. As we communicated in a recent RIPE Labs article, we will work with GÉANT as a test partner to learn more about the operational effects of introducing WiFi measurements to the RIPE Atlas system, in addition to the benefits we believe this could provide for the entire RIPE Atlas community. Please see the article for more details if you are interested: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-wifi-measure… We will continue to update you once we’ve begun work on this plan, and we welcome your comments in the meantime. Regards, Robert Kisteleki RIPE NCC

Your probe is currently disconnected
by Conrad Kostecki 15 Aug '17

15 Aug '17

Hi! I've applied for an Atlas probe v3 and got one via postage. So, I've connected the probe to my network. I can see in my DNSMasq logs, that the probe gets successfully an IP address. It can be pinged without any problems. But that's all. Even after 24 hours it's still reported not connected. I can see multiple LEDs: 1 (power): on 2: off 3: slow blink 4: fast blink 5 (button): on I can't find that in the FAQ, the LEDs should light different. The FAQ also did mention to try first without USB and insert USB later. Or try to replace the USB. Both cases did not help. If I connect my ThinkPad instead the probe with the same network connection (cable and port), it can access the internet just fine without any problems.. I've no clou, what could be wrong. Any ideas? Thanks! Conrad Viele Grüße Conrad Kostecki

SOS History empty since 2017-07-20
by Christian Schrötter 01 Aug '17

01 Aug '17

Hi, the last entry in my SOS History is from 2017-07-19, see screenshot [1]. My probe is still connected and working, but there should be two items per day at minimum, for each reconnect of my DSL connection after 24 hours. Looks like something is broken at the Atlas system. Could someone confirm this bug? -- Regards, Christian [1]: https://happytec.at/r/Xfaab

Probe recovery does not work
by Gil Bahat 27 Jul '17

27 Jul '17

Hi, I've finally managed to get a few USB drives to recover at least a few of my probes (I've spread about 3 dozen and only 2 are still online). But the stated recovery procedure does not work for me, with brand new 8GB keys. Is there any good way to see what's really going on with the recovery? the probes register themselves with the right addresses so I know connectivity and DHCP is ok, and yet they never recover. can the dhcp firmware be modified to try more aggressive recovery or better reporting of its state? Regards, Gil

Wifi measurements?
by Hank Nussbacher 24 Jul '17

24 Jul '17

When I start a new measurement, in addition to the standard measurements like ping and traceroute, I see a "wifi" measurement that appears for about 2 seconds at the end of the list and then auto-disappears. See attached screenshot. Explanations? Thanks, Hank

NSID option on the RIPE Atlas SOA measurements of the root servers
by Chris Amin 20 Jul '17

20 Jul '17

Dear colleagues, RIPE Atlas is currently running a series of DNS SOA built-in measurements* towards all of the root servers from all probes. During the recent DNS measurements hackathon** it became apparent that for some use cases it would be useful to have SOA queries from all probes with the NSID EDNS option set, in order to be able to match up responses with the particular responding instances in an anycasted (or load balanced) setup. We would like to ask for feedback on two alternative options for implementing this change. They are: 1) Enable the NSID option for the existing built-in measurements towards the nine root servers which support it. 2) Start a new set of built-in measurements towards the nine root servers which support NSID. The advantages of option (1) are that it will be possible to compare and contrast the two sets of results, and that historical data for the existing built-ins will remain consistent with the current results. A very simple analysis shows that there is no overall increase in query error rates through enabling NSID, but there are bound to be individual marginal cases where queries fail or produce different results with NSID set but succeed without it. The advantages of option (2) are that there will be no increase in result storage usage -- the current IPv4+IPv6 UDP SOA built-ins towards the nine supporting root servers adds up to about 80 results per second (~1.5% of the total results in the system). This could potentially be mitigated by reducing the frequency for these new measurements, but perhaps more important than the slightly increased load is the potential user confusion caused by generating and providing two very similar sets of measurements. Please let us know if you have any preference for which way we go on this, particularly if you have a (current or future) use case for this kind of data. Kind regards, Chris Amin RIPE NCC * https://atlas.ripe.net/docs/built-in/ ** https://labs.ripe.net/Members/becha/results-dns-measurements-hackathon

Update on the anchoring measurements change
by Johan ter Beest 20 Jul '17

20 Jul '17

Dear all, As described in the labs article here: https://labs.ripe.net/Members/alun_davies/balancing-act we have split the anchoring measurements. We are currently in the process of adding more probes to the new 'probe' anchoring measurements. We expect this to be completed by the end of this week. Please let us know if you notice anything out of the ordinary. Kind regards, Johan ter Beest RIPE Atlas Team
