You might want to take a look at what happened in the north-eastern
part of the United States not long ago. An early snow, while the
trees still had their leaves, knocked out power all over. Some
people did not get power restored for a week or more. I wold not
consider that a war zone, though I guess you could say the problem
came out out of the blue...

Do not forget about construction accidents taking out the power.
Backhoes do not just cut fiber optic cables... I saw a dump truck
take out a power line when the driver did not lower the dump box
before starting to drive away. And you never want to see what
happens when a crane hits a high voltage line.

Dumb question - when was the last time you tested your UPS? I mean a
real test, where you pull the plug on the UPS, and see if the system
responds as it should. Does the system do a full shutdown before the
power runs out?
You can NOT count on the UPS status display or reports from a smart
UPS if you have not had a power outage for a while. I have a UPS
here that reported everything was fine, and that it could provide 1
hour of power at the current load level. Guess what - it shut down
because of low battery less then a minute after pulling the plug.
Do not meddle in the affairs of dragons,
