(if that service goes down, everyone in my house gets mad at me)

I bought a PiZero and set it up as a redundant pihole for this reason. It’s slower because it’s wireless, but not super noticeable since it’s ‘just’ DNS. I have the router pointed at the main and backup all the time and if I need to do something (or break the main one messing with dockers) there’s still the backup until I get the main up.

I messed around with some High Availability configs where they both had the ‘same’ ip but could never get it working smoothly. I just use the teleporter functionality within pihole any time I update anything to keep them in sync, which is rare.

Only real reason IMO is dust can collect on the seam and it’s annoying to clean without taking the peel off anyway.

IDK why people get weird about it.
