Any explanation for this behavior? There is nothing unusual in the relay's logs and there was no reboot today. In my opinion it's strange that a relay suddenly disappears from the votes. If I got it right, usually an authority votes for "not running" if a relay can't be reached for some reason. But ALL votes excluded my relay starting today at seven am.

I've filed a ticket for what I think is the root cause:

There is indeed a bandaid in place so that relays generally recover from
this situation, but hopefully we can do even better.
