It depends on the installation. I worked at a number of service 
bureaus and ISVs, and none had a UPS or a generator.

One of our competitors (with government contracts) had both a 
UPS and a generator. Their system crashed after a technician had 
services the UPS, and hit a reset switch. Another time some 
batteries sprang a leak, on Christmas day, and they were unable 
to get service. The president and some VPs came in to shovel 
sand on the sulfuric acid - they were down for three days.

OTOH, my PCs have a UPS each, but now I live in an area with 
really flaky power.
