Early 80s. Brand new data center. Brand new hardware. Brand new halon system.
Facilities decided to test the halon system. They didn't expect the force of the dump. Shredded ceiling tiles everywhere. CEs were still picking pieces out of cabinets years later. So in case it dumped again, to prevent ceiling tiles from getting into the equipment, someone came up with the bright idea of putting sheets of plastic over all the boxes. Know how fast restricted air flow can cause problems?
