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

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

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.

check dns64/nat64 behavior ?
by Thomas Schäfer 21 Feb '20

21 Feb '20

Hi, is there a simple way to check the reachability of IPv6 targets by probes behind NAT64? e.g. If I try to ping www.t-online.de with Adress Family IPv6 I get immediately the error " No IPv6 address found for target" instead of "measuremnet created". Same problem exists for DNS measurements. Regards, thomas

Probes were incorrectly not tagged with the stability tags
by Chris Amin 21 Feb '20

21 Feb '20

Dear colleagues, Over the past month there have been issues with the "system-ipv[45]-stable-{1,30,90}d" tags, which were not applied to many of the probes that should have had them. This was caused by accidental data format changes from a backend migration. The issue should now be fixed, so probes will have the correct tags applied. If you notice any persisting issues then please let us know! Apologies for any inconvenience. Kind regards, Chris

atlas probe down
by MAYER Hans 19 Feb '20

19 Feb '20

Dear All, Our Atlas probe with ID 35603 is down since Wednesday exactly 12:00 LT. I unplugged power and powered on, but no success. After power on some LED's are blinking. Finally the power LED stays on and the LED next to it is blinking. But I can't ping this probe. Either on IPv4 nor on IPv6. We got this probe in summer 2018. So I can't believe it's EOL. Any ideas what I can do ? Kind regards Hans --

Can I issue a traceroute measurement with multiple targets?
by Vasileios Giotsas 11 Feb '20

11 Feb '20

If I have 100 IPs to target from a single probe, is it possible to create a single measurement with 100 targets similar to how I'd do if I wanted to target a single IP from 100 probes? I've read through the Atlas API documentation and couldn't find anything like that but it looks like some of the built-in measurements do that. Thanks, Vasilis

Atlas API stream broken?
by Teun Vink 10 Feb '20

10 Feb '20

Hi, Since ~13.30h CET this afternoon our Atlas data stream subscriptions (using the ripe.atlas.cousteau python library) stopped receiving updates. Earlier today we (at 11.27h) observed some issues with the backend where we received redis errors, which were resolved at ~12.09h CET. I heard these were related to some firewall issues, could these problem be related? Regards, -- Teun Vink BIT | teun(a)bit.nl | +31 318 648 688 KvK: 09090351 | GPG: 0xFC8B25D6 | RIPE: TEUN-RIPE
