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.
There’s so many ways to skin this cat, you may want to start with identifying the most crucial single failure point that concerns you.
Is it the router? Best you can really do is have good hardware and make sure it and your modem are on a UPS.
If it’s an ISP-provided modem, some enable remote management via a phone app, which can be done from anywhere by signing in to your ISP account.
Well, in my case the most crucial single point is the firewall.
The rest isn’t too bad
