Well, I think we're all missing the real point.  There is no way that one 
single system should be able to take down an entire ARTCC.  No matter what 
the system is, Unix, Windows, or a RTOS(which is what they should be running)  
there is always a possibility of failure.  While the nature of the problem 
may have precluded an automatic failover(unlikely), the system operator 
should have initiated a manual failover.  It seems to me that the root cause 
of this problem is system architecture design, not an implementation issue.
