We have five Crays here at Los Alamos and the MTBF is lots larger than
4 hours.  I don't know what the official figures are, but we have had
some machines run for several weeks without unscheduled down time.  In
fact one machine ran long enough without down time that a slight error
in the clock rate had time to accumulate into a noticable error in the 
time of day.
