This has now happened again, on the same bridge, showing off-line to the metrics, but the logs showing it running with activity taking place.

Guess I'll keep an eye on the metrics to see if it pops back to available.

I'm wondering how often this might be happening, because I don't check the metrics that often and the instance documented below didn't change the Uptime or Last Restart to indicate anything had happened.  So unless I notice while it's in this state, like now, I have no way of knowing if it happens regularly or not.

Cheers.

You are running 0.4.5.8, maybe updating to a newer version of tor will help?

I wonder whether that is another instance
https://gitlab.torproject.org/tpo/core/tor/-/issues/40424. Hard to tell,
though. Does that issue happen regularly?

I didn't touch anything, and this morning the metrics say the bridge is running normally, with an uptime of over 125 days.

Looks like it might have been a metrics issue, not the bridge itself.

Cheers.
