It also depends if you're renting a dedicated server, vs cloud/VPS. AWS/Google/Azure deal with virtualized systems that can be moved around to another server easily.

OVH has a lot of dedicated servers as well though, so if you're using one of those then it can't be moved very easily to avoid downtime.

Just to note - only google does live migration (with ~100ms blackout) with others you will take some downtime anyway (assuming the remaining zones even have enough capacity to fit everyone)

Google never migrates to a different physical location, so it wouldn't actually protect against a whole class of issues (major flooding, war, employee strike, etc)

Zones are often in separate locations but only within a few miles so yeah. Also i think they won’t even migrate inter-zone so there’s that
