After being home for weeks, I went away for business, the 1st night away there was a brief powercut and the firewall (on a UPS) seemed to get stuck.

So, that's no DNS, DHCP, or connectivity between wifi and LAN... All due to (admittedly aging) hardware issue.

Since then my entire home system has had issues whilst it all settles down.

It made me think about getting some redundancy into the system to handle a single failure.

So,.can you give me any insights into High Availability like CARP (for pfSense), VM failover (on Incus?), mesh wifi, Home Assistant, etc?

Of course there are going to be single points, like ISP line, etc, but seems like something to test out.
