At PPOE -many
The building power was known to be on the edge of reliability and I wanted all the servers out of my office (!). So while looking at the circuit breakers I found the one labled "Board Room" was too hot to touch. Checked in board room and there was nothing even plugged in. So I pulled the breaker to see what would go out.
All the servers.
Seven hours later I had them back, and a few days later the MD's permission to have the building rewiring I had been requesting for months. And a separate, air-conditioned space for the servers.
She didn't fire me for that but for saying that Linux was the way to go for movie render farms not NT4.0 (yes that long ago).
