Yes, I hear UPS's all the time, down in the machine room. They're the boxes
that are always beeping to tell us their very few years old batteries arent
working anymore. We connect them to our uninterruptable power, which is fed
by two separate power stations and some device switches power immediately
if one feed loses power. That device hasnt worked properly in the 12 years
its been installed...

So much for a 12-13 year old, 'modern' computer science building.
