It's time for the monthly servicing of this server room's air conditioning, so a sysadmin pilot fish meets the AC guys when they arrive.
"The vendor had sent a team comprised of people who had never visited our office before," says fish. "I accompanied them to the server room, then headed back to my seat in the adjoining room to answer a phone call."
But fish's heart stops when he hears the AC guys screaming for help.
He rushes back to the server room, and sees in an instant what's happened. They've opened a servicing outlet without making sure the valve was closed -- and water from the high-pressure chilled water line is spraying all over the server room.
