Reminds me of a time...
...that an airport I was working at had a water leak in the middle of the night. The contractors went under the check-in desks and isolated the individual UPSs in the area that was affected, just to be on the safe side (they weren't actually wet). Having stopped the leak and cleaned everything up, they plugged the UPSs back in again.
About half an hour later, check-in started, everything was going fine, until that entire bank of check-in desks all died within 2 minutes of each other, and chaos ensued in the middle of the morning rush.
Turns out the contractors hadn't plugged the UPSs back into the mains - they'd plugged them into themselves...
