	It's always fun to see the media distort things.  This bit about
nuclear war has been a favorite for a couple of years now.  The phrase used
during the development of the technology was "hostile (battle)field
conditions".  Conventional scenarios are all that is reasonable to plan
for.  Nuclear ones, per se, weren't part of the discussions.  As folks
might have suspected, not much survives except roaches and they don't carry
large enough packets fast enough.

	The DNS has been able to support multiple hosts under the same name
for quite some time (say around 10 years) whereas the round-robin technique
is perhaps 2 years old.  It was developed for load-leveling, not robustness.
