Probe disconnected – cold reboot required (ctr-ams08)
by Christian Schrötter 13 Nov '17

13 Nov '17

Hello Atlas-Users! Do you have any problems with your probes today? Mine disconnected two times in the last ~15 hours and never came back online. Internet is stable and SD-card looks ok. I had to force a cold restart to get it back online. Strange thing, it's the first time in two years. Old uptime was 99 days... :-/ -- With kind regards, Christian Schrötter

Dear colleagues, Here is a summary of a research paper written by Wes Hardaker, Wouter de Vries and Ricardo Schmidt: Verfploeter: Broad and Load-aware Anycast Mapping IP anycast provides DNS operators and CDNs with automatic fail-over and reduced latency by breaking the Internet into catchments, each served by a different anycast site. https://labs.ripe.net/Members/wouter_de_vries/verfploeter-broad-and-load-aw… Kind regards, Mirjam Kühne RIPE NCC

Recent TLS supported by probes?
by Stephane Bortzmeyer 13 Nov '17

13 Nov '17

I cannot get the certificate for <https://dns-resolver.yeti.eu.org/> (measurement #10174881): "alert" is "{u'description': 40, u'level': 2}". It works with other, more "mainstream", HTTPS sites (see #10174883). I suspect this is because the probes don't handle the recent TLS stuff. Can anyone confirm or infirm?

Atlas Measurements
by Tom Glass 13 Nov '17

13 Nov '17

Hello all, Hope you are having a great weekend. I just stopped by to ask if you guys would know where/if I can add new probes to an existing measurement. A new probe has appeared in the area we are monitoring and I was hoping there was a way of adding it without recreating the measurement? Cheers, all, Tom

Odd queries from probe
by Jared Mauch 10 Nov '17

10 Nov '17

While doing some debugging of my home network, I noticed some odd queries from the probe, namely this one: 02:28:36.921622 IP6 fe80::a2f3:c1ff:fec4:479f.51123 > 2001:558:feed::2.53: 23808+ A? 12920.atlas.ripe.net.b61065696c194ac3. (55) Is this some captive portal/wildcarding detection, or perhaps some other software issue? curious, - Jared
