Re: [atlas] Probe #1000165 showed as down in tab#status
So whilst volunteering as NHS vaccination stewards we still awaiting up probe
notifications by email which we have asked for before so we can see on our
mobile devices.

Well, in this curious case the machine ("controller") itself thought it
*should* have IPv6, which indeed was the expected situation. Yet it
didn't. Therefore it was very confused about its own state and as a
safety measure it told its probes "hang on a minute while I figure out
my own situation" :-)
We designed the controller-probe protocol so that it can handle case
such as this; that is, the probes will try reconnecting, and in really
bad cases the system drives them to a different controller. In the
meantime they execute what they were asked and store results.

Anyway : probe is ok for 5 hours, 42 minutes
Good, good!

I know people that have preached "if you do IPv6, *always* remember to monitor IPv4 *and* IPv6, all the time, for all services" for like 15+ years now... And I've been told that you have the largest monitoring system ever at your disposal... :-) Gert Doering -- NetMaster -- have you enabled IPv6 on something today...?

Re: [atlas] Probe #1000165 showed as down in tab#status
Hi Jacques, Thank you for reporting! There was a network maintenance in Hetzner last night. Few days before the ctr-fsn01 was reinstalled. Due to minor network misconfiguration the controller's IPv6 connectivity was not restored. Now the problem is solved.
