Nova Network Corruption

My office and supporting network gear is wired with UPS protected power sockets.  Today, our house cleaner plugged the vacuum cleaner into a UPS socket.  A short while later, the UPS protested and I had to do a "hard" reset of the UPS.  The network came back up, but my Nova started showing an error that it couldn't detect the network.  Surprising, because I was controlling it with the App and with Roon over the wired network.  It appeared to be the wireless network that it couldn't see, and no amount of entering the details would bring it up.  Hard reset of Nova!  But then the remote wouldn't work and wouldn't pair.  Hard reset of the remote! (remove batteries). Re-pair and everything is now up and running; no error messages and all networks showing their addresses on the Nova.  And Nova playing music!

So, a learning experience.  Nova and its remote don't like having the network go down.  And hard resets seem to be needed in order to bring things back up fully.

Has anyone else had this experience?
