oh, and even with that, where I had input, I spec'd at least a 250 VA class
APC UPS (with line conditioning and surge protection) for the computer
systems in my department.

even with 'preferred' status, and dual independent feeds, hospitals are
required to have enough internal generating capacity (and auto start/transfer
capacity within 30 seconds) to handle 'critical life safety' needs (for at
least 8 hours, IIRC). this would include power to run ventilators,
monitors, minimal lighting, and often at least one elevator.
And as several hurricanes (and flooding along the Miss/MO/OH system) have
demonstrated, it is NOT a good idea to have all of your generators in the
basement.

I worked at this Nation's largest municipal utility.
It was considered a "preferred" installation, much as police, fire
and hospitals, and we had no reason to employ a generator.
Our headquarters building, where all our mainframes were located, had
two independent 34.5 kV feeders from two different distribution
stations.
Even during the three major earthquakes which devastated portions of
L.A. during my employment there, we never had as much as a glitch at
my residence in the Brentwood District, nor at my place of employment
at 111 N. Hope St.
Nearly every mainframe installation had the same opportunity to
obtain "preferred" status, all it cost was $$$, but most did not
elect to do so.
