[tor-relays] Metrics shows my relay down. But it's not.

[Eddie]

The metrics is showing one of my relays 
(40D13096BBD11AF198CE61DEE4EAECCE5472F2E7) as down for around the last 3 
hours.  Logging in to it, I see everything running normally.

This server has also lost a bunch of flags for no apparent reason, so 
I'm not sure if they're connected.

Cheers.
