alt Hacker NewsSounds like crappy UPSes. Even the cheap old used eBay Eaton UPSes I have in my homelab have a setting for "Auto restart" and the factory default setting is "enabled".
But even rackmount UPSes are more of an "edge" sort of solution. A data center UPS takes up at least a room.
I assume that datacenters UPSes are better, but I’ve never used one except as a consumer of its output.
But I’ve had problems with UPSes that advertise auto-restart but don’t actually ship with it enabled. And that fancy APC unit was sold by fancy Dell sales people and supported directly by real humans at APC, and it would still regularly get mad, start beeping, and turn off its output despite its battery being fully charged and the upstream power being just fine (and APC’s techs were never able to figure it out either).
