Kjell's Law: the cost of a platform eventually exceeds the cost of the one it replaced. But each cost is in a different budget.

We seem to have replaced cooling and power and a grumpy sysadmin with storage and architects and unhappy developers.

I've never worked in a data center that did cooling and power correctly. Everyone thinks they're doing it right, and then street power gets cut - there's significant impact, ops teams scramble to contain, and finally there's the finger-pointing.

The colo I’m used to has survived multiple switch overs to backup and then to diesel generators without a blip that I could detect.

I say “I’m used to” because having things there has spanned more than one job.

One power outage was days to a week. Don’t recall exactly.

It’s possible to do it right.

Yes it's possible. But it's not cheap. If you buy a bunch of UPS and a few generators (you need more than one, in case it doesn't start) and don't maintain them regularly and test them regularly that's when you get some bad surprises.
