It is, I think, a measure of the cynicism extant in IT departments that when our Big Blue Box (it's black, actually, but that's beside the point) signaled that it was in distress, the sysadmin thought it could conceivably be a prank woven into IBM's microcode, set to trigger on the first of April. Instead, it turned out to be a disk drive gone troppo. We lost nothing datawise, but there will be extra laundry this week.
