Both probes lost all internet connectivity for a couple of hours. I have no idea what happened but Atlas traceroutes stop at hop 1 (and don't even reach the local router).
Yes, but the problem was not with the networking infrastructure: like I have reported each time, none of my other equipment has had any connectivity troubles at these times, and both probes remained inaccessible until power-cycled, when immediately they are fine again. The "couple of hours" you cite start when the issue begins, and ends only when I arrive to power-cycle them. The only sort of thing that makes any sense to me is that something occurs that triggers the probes and only the probes to lose their minds. Possibly an electrical power aberration or a networking hiccup sends the probes into a state that they cannot recover from on their own. But even the 'power aberration' explanation seems unlikely, since the two power feeds are dis-similar enough that I would not expect any surge or whatever that hits one to hit them both, and to hit in a way that only RIPE Atlas probes are affected. Has anyone else experienced electrical power disruptions that send RIPE Atlas probes into a state like the one I described in my initial message, while no other nearby equipment notices any problem? Thanks.
