Atlas #50012 handed over..
by Geert Jan de Groot 09 May '18

09 May '18

Hi, Lia just handed over probe 50012 (that's the new hardware version), and I plugged it into the AIS/AfriNIC network here in Dakar. Can you please make this probe "mine" so I can administer it? For the next few days, will try a few things (and please do so yourself!) My existing probe is 16233. Currently it is powered through the USB port of another device, I will try PoE later (it will switch to 100 mbit then). Currently it seems to do 1gbit. Will make notes and share with you. GJ

Minor change in the API Participation Requests endpoint
by Agustin Formoso 03 May '18

03 May '18

Dear Atlas users, We're planning to roll-out a minor change in the API Participation Requests endpoint. We'll be changing the response that gets sent out when a Participation Request is submitted. Although minor, the change may break your code if you are making use of the response. Current response example: [35878] Future response example after roll-out: { 'request_ids': [35878] } We plan to put this change into production two weeks from now. For those who don't know what Participation Requests are, they allow you to add or remove probes from a pre-existing measurement. You can find more information in https://atlas.ripe.net/docs/api/v2/manual/participation_requests.html Regards — Agustín Formoso RIPE NCC

RIPE Atlas probe status issues
by Chris Amin 26 Apr '18

26 Apr '18

Dear RIPE Atlas users, There were various issues relating to the recorded status of RIPE Atlas probes over the weekend. This was brought to our attention by internal monitoring and information provided by users on the mailing list. Throughout this period most probes did actually remain connected to controllers, and measurement results were collected as normal. The side effects included: * the number of probes reported as connected by the system was lower than it should have been * the status (connected/disconnected) of many probes was incorrect * new measurements took longer than usual to start * fewer probes than usual were available for new measurements, leading in some cases to “no suitable” probes messages when trying to schedule new measurements * various system tags were incorrectly applied, including many probes being marked as having USB problems when this was not the case * temporary discrepancies with crediting/debiting of RIPE Atlas credits for the connected time of probes The issues were caused by a bug fix deployment at Friday 9AM UTC where a package was accidentally downgraded causing a regression to an old bug in the task handling of the central system. This bug caused a backlog of messages to build, slowing down or stopping the registering of various status messages in the system. Problems built up gradually as the backlog increased, until the root cause was identified on Sunday morning. The issue was then fixed and the system stabilized completely by about 10AM UTC. We have identified procedural and technical solutions that will stop this problem happening again, and are looking at ways to improve our monitoring of these kinds of issues. We apologise for any inconvenience or confusion caused by this event and would like to thank all of you who took the time to notify us of what you were seeing. Kind regards, Chris Amin RIPE NCC

Hidden measurements
by Marty Strong 25 Apr '18

Does anybody else find that measurements you’ve marked as hidden by clicking on the eye next to it disappear as expected, but don’t show up on the hidden tab (https://atlas.ripe.net/measurements/?page=1#tab-hidden)?

25 Apr '18

All of my RIPE Atlas measurement requests (pings in this case) are suddenly failing with a status "title" field value "Forbidden". Why is this happening?

paris traceroute output
by Radim Hrazdil 23 Apr '18

23 Apr '18

Hello all! I'm struggling to understand how is the number of paris variations reflected in the merasurement output. If I run paris-traceroute on my machine, the output of a single hop looks something like this: 6 P(16, 16) HOSTNAME (IP):0,1,2,3,4,9,10 4.534/6.072/15.130/2.957 ms HOSTNAME (IP):5,6,7,8 7.641/10.282/13.119/1.965 ms What I'm reffering to is this part: (IP):0,1,2,3,4,9,10, which says which probe packets 'visited' this particular router. I don't understand, how is this reflected in the measurement output. I have never encountered situaton in which 'from' fields within one hop would differ. This would suggest that no load balancing has been encountered, but that seems unlikely to me. Thanks for any replies, Radim Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

dnssec validating system tag?
by Tapio Sokura 23 Apr '18

23 Apr '18

Hello, I was looking at the probe system tags at https://atlas.ripe.net/docs/probe-tags/ when dnssec validating resolvers came to mind. Has there been thoughts about making the probes do dnssec resolver statistics gathering? I.e. how many / which probes are configured with dns resolvers that do / don't do dnssec validation? Tapio
