<p>You were involved a lot earlier than I was. Perhaps you could
comment on how much folks thought about fault-tolerance in the
early days. It's always struck me that things like
continuity-of-operations, in the face of node & link outages,
and no-single-point-of-failure, were baked in from the beginning.
You know - all the stuff that would allow the net to survive
everything from backhoes to natural disasters, and coincidentally,
nuclear war. <br>

<p>On the physical side, the early IMPs were pretty rugged boxes
(not so much C/30s and such). Were any of the IMPs built to
withstand EMP?</p>
