Re: FAA's many soft spots

In this case it appears the major problem was a bunch of adjacent processors were damaged by the fire. They could have been in a containable environment so it would not spread. They also could have had redundant processors to take over.




That too, but it also sounds like a case of problems of co-located communication lines. I'm sure everyone considered single-point failure of individual boxes, but I'm not sure as they considered single-point failure at the room level.

At some point you have to consider single-point failure of the entire tower. And that may be what mode they're running in now.

Perhaps a room-level fault was considered too remote.
