Hi - Discovered this morning that the zigbee network was offline on my C5. Restarting the hub seems to have restored it - but not sure what would cause that. I looked at the logs and didn't see anything obvious (other than hubitat log reporting it offline earlier this morning). I didn't see any devices reporting high activity or anything like that.

Crap new firmwares. that caused it
Could have been a build up of things over time? Zigbee is the 1st to go if the hub gets bogged down, I normally see it on one of my hubs when there was a lan device that went wonky a few days earlier. Then it seem to take up to a week before it then causes a issue.
Reboot and your good to go.

Considering nothing has touched the c5 zigbee stack in several years, do you have proof of this?

Generally speaking, I've found a controlled shutdown and power cycle to be better than a reboot, especially for Z-Wave. I think it might be true for Zigbee as well, but I don't know.

It is my understanding that the Zigbee also needs the hub powered off with the power plug pulled in order to be rebooted.

This is something to definitely check. In particular, if you have a cloud based application that is running wild, or a poorly constructed rule, it can bring the hub to a halt.
Errors in the logs need to be addressed. Also look at App Statistics and Device Statistics and see if anything is using excessive resources.

Hi thanks. As I mentioned above, there were no errors in the log that stood out, and both app and device statistics showed low usage overall. (less than 20% busy as I recall). The home assistant device bridge is usually the heaviest load.
