Releasing inert gas from fire suppression units that were over pressurized resulted in an extremely loud noise – causing cabinets full of hard drives to vibrate – which got transmitted to the read – write heads of the drives.
Amazing sort of outage + data loss, and this time the physical security plant chief gets to write up the RCA.

Another unexpected result when we had an all-out Halon test: thick fog, apparently from cold gas and somewhat humid air. I'm glad to have been watching through windows. Visibility in the room dropped to zero.
