Software probes offline since updating to 5010-3
by Paul Eagles 12 Mar '20

12 Mar '20

Hi all, About an hour ago I updated my 4 software probes (1000136, 1000137, 1000149 & 1000177) to 5010-3 from 5010-1 and they're all still showing as offline. For each probe I went through and updated the keys within a minute or so of the installation finishing so I don't think that's the problem. It shouldn't be an internet connection issue, they're all using the same connection as they were prior to the update and prior to the update all 4 probes were connected OK. Plus I have a physical probe at home in the same location as one of the software probes and that physical probe is showing as online. One of the software probes has been rebooted but that didn't seem to make any difference. Checking the running processes on the host everything appears OK, I see 2 instances of the ATLAS binary running. Am I missing something or just being impatient? Cheers, Paul.

(not) disconnected probes
by Romain Fontugne 11 Mar '20

Hi, I found that the following probes are reported disconnected for several hours a day, more or less at the same time, but all their built-in measurements are there and seem normal: https://atlas.ripe.net/probes/32639/#!tab-network https://atlas.ripe.net/probes/28818/#!tab-network https://atlas.ripe.net/probes/19107/#!tab-network https://atlas.ripe.net/probes/14831/#!tab-network https://atlas.ripe.net/probes/11982/#!tab-network These probes are in different ISPs and locations in Japan. Any idea why this is happening? something funky on the controllers side? Thanks, Romain

New on RIPE Labs: What’s the Deal with IPv6 Link-Local Addresses?
by Philip Homburg 11 Mar '20

Dear colleagues, Stephen Strowes, Emile Aben and I published a new article on RIPE Labs on how link-local addresses in IPv6, and specifically the '%eth0'-part of link-local addresses, can have an impact on RIPE Atlas measurements. https://labs.ripe.net/Members/philip_homburg/whats-the-deal-with-ipv6-link-… We think this will be an interesting read for network operators and others who are using RIPE Atlas measurement data or are interested in IPv6. Kind regards, Philip Homburg RIPE NCC

Broken traffic graphs in latest firmware (5010)
by Philip Homburg 10 Mar '20

10 Mar '20

Hi, A change in the RIPE Atlas probe code to make reporting traffic statistics optional in software probes (and disabled by default) has the unfortunate side-effect that reporting of traffic statistics is now disabled on Version 3 and Version 4 hardware probes, as well as all anchors. This change was rolled out in firmware version 5010. Unfortunately, this effect was not spotted during testing. We will roll out a new firmware release that corrects this issue in coming weeks.
