The pain is passed. One by one the servers crashed due to a NaN bug (Not a Number).
I found the problem in the recent fix to the attitude indicator. An arc sin function was passed an argument more than 1 or less than -1, which results in a NaN result. This destroyed the transformation matrix of the spacecraft involved and resulted in a server crash.
One by one the servers were updated as they crashed, over the course of about 8 hours. They have all been updated with the fix now and they seem to be running smoothly.
