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.

Low tech options: a smart plug that power cycles if it can’t ping eg google and have your edge devices plugged in there, or a timer that reboots the firewall at 0200 daily. I haven’t implemented either of these, despite having a network other people rely on about 400km from my house. I should remediate that…

I have decided dual firewalls are silly without dual internet and dual power, as both those things go down more often than my FW.

I have two instances of pihole on two hosts, because I block dns outbound to the best of my ability.
