Before pulling the power on the hub, please try to access it via its Diagnostics Web Page at http://[yourHubIP]:8081
This is the safest way to manage the hub if it is not responding at http://[yourHubIP].

I could even see it on the network, so that was impossible.
Am I correct in thinking that except the network devices and interfaces, everything should keep working even if it loses the network connection? That's one of the things that attracted me to it over ST.
As long as the hub doesn't reboot while disconnected from the network - yes, it should all keep working.
If it reboots with no network connection then the time will be incorrect (there is no internal Real Time Clock, so it has to get the current time on every reboot), so anything relying on time will not work as expected. Which is reason 1 that you should have the hub on a UPS (if it is not already).
As mentioned, pulling the power without doing a graceful shutdown runs a high risk of corrupting the internal database. That is reason 2 to have the hub on a UPS (if it is not already).

It's a shame it doesn't have a 'reset' button for a graceful reboot. If you can't access the UI you're stuffed and can only pull the plug. For the price of a push-button that seems a bit short sighted.
I would imagine that the scenarios where you don't have access to it over the network, and need to boot it right then, are pretty few.
But yes, it would be nice if there were a way to gracefully shut it down from the hardware.
If you lose contact with the hub after a reboot your router (or other DHCP source) may have assigned a new IP address. There is a Find Hubs function on the Portal.Hubitat.com page. I use the Fing app on my phone.

I'd also assign an IP in your router to the hub so it doesn't change later.

Absolutely true. All my servers, printers, etc have assigned addresses. I was just trying to give him the least amount of information to get back on track.
Yes, it has an IP assigned to it. It's back now after three reboots. Seems odd. What there is in the log is about network issues, but there isn't much there.
Thanks for the suggestions. I guess it's a combination of investigating what devices may have caused it to to hang and cross my fingers and hope!!!
Netgear and ASUS equipment have some auto negotiation issues. Here is a post from @bobbyD about this issue. https://community.hubitat.com/t/c5-hub-lan-connection-issues-with-network-devices/30565
