Sure an APC/UPS is pretty much necessity but I've also had services that lost their mind when the internet went down for more than a few mins. I also personally wouldn't rely on a UPS keeping the server up long enough for power to be restored (depends on capacity and load, etc.). Sometimes a graceful shutdown paired with WoL is better.
Lots of ways to approach these issues which is why infrastructure engineers get paid well.
It's not to keep it up untill power is restored. It's to keep it up if it was a minor outage and cleanly shutdown if it isn't.
If some is using it purely for weathering an outage they're doing it wrong.
