One of the funny things about the place I used to work (which will remain unnamed) was how the UPS folks were always testing their systems by pulling the plug on the main power to the building. The problem was they apparently hired untrained monkeys to wire up the UPS systems (which were just a few rooms chock full of batteries) and managed to kill power to the entire building (including the computer rooms) at least once every three months. This was doubly annoying because we had well over 100 full RAID racks (with 80 disks in each rack) in the facility. Hard drives, as most of you probablly know, are most likly to fail on boot time, so every time one of the brain cases managed to kill the power in the CRs, we had to spend the rest of the day replacing failed RAID drives.
