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.
