Both manage air conditioning, power, fire suppression, etc and ultimately live and die by their uptime, so they have an incentive to do it right.
You can have a pretty sizable server capability on modern hardware before you need to touch that.
I can serve what... 1M users? perhaps 10M users? before my server equipment needs it's own AC unit. Depending on the system needs, architecture, complexity, and perhaps language. I can get 100Mb-1Gb of egress bandwidth pretty easily at most residences, let alone business locations.
I can buy battery backup capacity for cheaper than ever, can probably skip the generator. If you go multi region maybe even skip the deep backup power, for just enough to get clean shutdown, and just fall back early.
It's never been easier to do hosting than it is now. If you get your head out of the clouds anyway.
