My favorite where I used to work was the once a month Wednesday 5 AM 
generator tests.

This is where they kill the utility power and see if the generators 
would kick on and transfer power to the "emergency" outlets.

Always had a bunch of stuff go down because it would do weird things 
that even the UPS's couldn't cope with.

I dreaded the Wednesday morning "daily service review" meetings on those 
days because we would always have a bunch of severity 2's and have to 
convene a service recovery team.

Then there was the time the 1A data closet was 104 degrees for over a 
week.  Killed the batteries in the UPS and didn't do anything good for 
the router and switches.

A damper failed in the closed position.  Calls to the facilities 
department always got the "We're working on it" answer.  We ended up 
propping the door open and putting a big floor fan in the closet.

The 3A closet had a permanent floor fan because no one wanted to pay to 
  upgrade the cold air delivery to the closet.  They kept expanding and 
we kept adding network gear but no one would pay attention to our heat 
load data.

Working for a big corporate IT department wasn't a lot of fun at times.
