Cooling failure, hexagon forced to be shut off

Due to a double cooling failure (primary plus backup) for the building-provided chilled water supply, we were forced to shutdown hexagon due to over-temperature in the room.

Update 17:30: we hope to have the cooling back Thursday morning.

Update Thursday 10:00: we have now partial cooling and have started the machine and allowed logins. Until we know more about when we will get full cooling we have a system reservation on all nodes, you can add jobs to the queue but they will not start until we remove the reservation.

Update Thursday 11:00: we have now restored 1 of the cooling machines to operation so we have now full cooling, and reservation is removed.
