The data center might be... but are all fiber routers, amplifiers, PoPs etc. along the line from the datacenter to the hospitals and other healthcare providers backed up as well?

Particularly the "last mile" often enough is only equipped with batteries to bridge over small brownouts or outages, but not with full fledged diesel engines.

And while hospitals, at least those that deal with operating patients, are on battery banks and huge ass diesel engines... private small practices usually are not, if you're lucky the main server has a half broken UPS where no one ever looked after that "BATTERY FAULT" red light for a year. But the desktop computers, VPN nodes, card readers or medical equipment? If it's not something that a power outage could ruin (such as a MRT), it's probably not even battery backed.

There's a German saying "the emperor is naked, he has no clothes". When it comes to the resilience of our healthcare infrastructure, the emperor isn't just naked, the emperor's skin is rotting away.

Just pointing out that none of those non-data-center buildings are data centers.

I really doubt the classification of "data centers and other large, non-critical power consumers" extends to telecom infrastructure.
