Many years ago I was being shown the server room for the first time. They asked me to unplug a certain box. I unplugged everything on one power strip. Panicking at the drop of ambient noise in the room, I quickly plugged it back in, but... I have no idea why they didn't use UPS, but it took many critical servers offline and caused a few hours of headaches for everyone. Come to think of it, that was the last time I was allowed in the server room. Lessons learned - don't let developers in the server room.
