I was in another country when there was a power outage at home. My internet went down, the server restart but couldn't reconnect anymore because the optical network router also had some problems after the power outage. I could ask my folks to restart, and turn on off things but nothing more than that. So I couldn't reach my Nextcloud instance and other stuff. Maybe an uninterruptible power supply could have helped but the more I was thinking about it after just didn't really worth the hassle anymore. Add a UPS okay. But why not add a dual WAN failover router for extra security if the internet goes down again? etc. It's a bottomless pit (like most hobbies tbh)
Also (and that's a me problem maybe) I was using Tailscale but I'm more "paranoid" about it nowadays. Single point of failure service, US-only SSO login (MS, Github, Apple, Google), what if my Apple account gets locked if I redeem a gift card and I can't use Tailscale anymore? I still believe in self hosting but probably I want something even more "self" to the extremes.
This also makes self-hosting more viable, since our availability is constrained by internet provider rather than power.

Also generators are still cheap compared to batteries?
For longer outages there is an outhouse with triple-redundant generators:
- Honda c. 2005
- Honda c. 1985
- Briggs & Stratton c. 1940
The “redundancy” here is that the first is to provide power in the event of a long power outage, and the other two are redundant museum pieces (which turn over!)
