The only realistic concern for me here is the ISP failure. Even then, if I really wanted to I could have both AT&T and Spectrum uplinks with an LACP bond.

I have enough battery backup to run my rack for about 30 minutes, more if I shut down a node. That’s more than enough time for me to set up my generator and route power; it has an extended gas tank and can power the rack, fridges/freezers, fans, etc. for over 24 hours. I periodically run drills on this to ensure it’s doable, and that the gear works as expected.

If I’m not home, then yes, the latter would fail. Dual hardware failure is an unlikely scenario; single node failure is handled between K8s and Proxmox clustering.
