Re: [atlas] Probe location obfuscation

I would add to it additional problem that some hosts obfuscate probe location even more. For example you can find probes which in reality are located in US but are marked as CN or probes which are in reality in Wisconsin but are marked in California. Of course these are extreme cases. I guess most hosts just put a pin with probe location just somewhere around where it's locate as long it's in the same city. I don't remember, as a host of 3 probes, to get any precise recommendations how to mark probe location. Personally I just put a pin in city district where probe is locate.

Hi Christian, Thanks for your email brother. ...imho, it's a very useful idea!

Probe location obfuscation
by Mccherry, Paul (Student) 25 Mar '21

25 Mar '21

Can anyone confirm the geo-location obfuscation of probes as being up to 1km as per https://atlas.ripe.net/about/faq/#are-the-locations-of-probes-made-public I am a Phd student carrying out research on the RIPE atlas platform and an early result seems to indicate 1 probe has an obfuscation of 10km distance but this may be an anomaly or perhaps something not taken into account as yet.

Join the RIPE NCC Open House: Internet in Turkey: 24 February 2021, 11:00 UTC
by Vesna Manojlovic 26 Feb '21

26 Feb '21

Dar all, You're invited for an open discussion with the RIPE NCC about the Internet in Turkey! We are hosting a RIPE NCC Open House for our members and other Internet stakeholders in Turkey on Wednesday, 24 February at 11:00 - 12:30 UTC and invite you to join the discussion. The RIPE NCC Open House is a ninety minute remote session where RIPE NCC staff, community members and industry experts can meet up and share insights, feedback and support. https://www.ripe.net/participate/meetings/open-house This session is focusing on the Turkish Internet community. We will be discussing various topics including: * The state of the Internet in Turkey and across our service region * How RIPE NCC tools and measurements can help operators (RIPE Atlas, RIPEstat, RIPEIPmap, etc.) * Improvements that the RIPE NCC can make to help operators in Turkey * IPv6 deployment * Local community development and the support available from the RIPE NCC Want to join in? Register for the RIPE NCC Open House https://meeting-registration.ripe.net/meeting-pub/registration?0&meetingId=… Looking forward to seeing you online!

New on RIPE Labs: RIPE Atlas Big Data is Back
by Alun Davies 23 Feb '21

23 Feb '21

Dear colleagues, At the beginning of the year, RIPE Atlas users started encountering delays in data retrieval and an overall drop in the responsiveness of the system. With service having gone back to normal earlier this month, we take a look at what caused the problem and what we're doing prevent it from happening again: https://labs.ripe.net/Members/paul_de_weerd/ripe-atlas-big-data-is-back Kind regards, Alun Davies RIPE Labs Editor RIPE NCC

Re: [atlas] [mat-wg] RIPE Atlas testing of reserved IPv4 addresses
by Robert Kisteleki 18 Feb '21

18 Feb '21

Dear All, A little bit of poking since there were no reactions to this question on the MAT mailing list. Before embarking on evaluating what it takes for RIPE Atlas to contribute to this, I'd like to ask for some input from the community; is this something we should spend energy on? More specifically, would it be worthwhile for us to spend time on evaluating the cost of / implementing such measurements in RIPE Atlas?

RIPE Atlas Measurements packets sent number not always 16
by Debora Marettek 17 Feb '21

17 Feb '21

Dear RIPE NCC, for my ping measurements, I incremented the number of sent packets to 16. Now I noticed that in the measurement with the ID 28779821, the probes didn't always send 16 packets, sometimes, albeit rarely, only 7 or 3. Below you see an extract of the packets_sent data of Probe 52673. Now I wanted to ask what could possibly be the reason for that phenomena. Kind regards, Debora Probe: 52673 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 5, 1, 9, 16, 16, 16, 14, 16, 16, 16, 16, 8, 13, 6, 7, 6, 6, 16, 16, 12, 16, 16, 16, 16, 16, 10, 11, 10, 7, 6, 16, 4, 16, 16, 16, 16, 4, 7, 15, 6, 9, 12, 11, 7, 8, 11, 6, 5, 13, 13, 13, 5, 10, 16, 16, 7, 7, 9, 7, 7, 7, 9, 16, 16, 11, 4, 7, 16, 7, 2, 8, 16, 4, 6, 8, 16, 7, 8, 6, 5, 8, 8, 9, 8, 7, 4, 3, 10, 1, 2, 11, 6, 16, 8, 12, 6, 11, 10, 11, 8, 12, 12, 12, 11, 8, 16, 6, 5, 5, 9, 10, 6, 10, 7, 9, 10, 9, 11, 8, 8, 11, 7, 12, 7, 11, 9, 13, 2, 10, 12, 10, 7, 9, 16, 13, 5, 4, 7, 8, 6, 5, 7, 6, 7, 9, 9, 9, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 4, 9, 4, 6, 8, 6, 11, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, <https://atlas.ripe.net/measurements/28931367/>

Re: [atlas] Updating probe ssh pub keys via API PUT/PATCH requests

Hi RIPE Atlas, Was reading through the documentation yesterday... Is there a specific reason why it is NOT possible to update probe (ssh) pub keys via authenticated API PUT/PATCH requests? https://beta-docs.atlas.ripe.net/apis/metadata-reference/ -- Best regards, Chriztoffer Hansen

Measurement Result Broken
by r.sommese＠utwente.nl 10 Feb '21

10 Feb '21

Hi everyone, I am getting trouble getting results for ping measurements. Looking at the web portal and JSON results, they are both empty. Measurement ID: 29049476 I also checked from the account of a colleague, same story. There is something broken in the pipeline? Best, Raffaele Sommese
