	I can believe parts of the power grid, but most comms
infrastructure is fiber... and I'd really be surprised that peering
points and major server facilities are vulnerable to the sort of
EMP that a CME would cause.   And most have pretty good backup
diesel or gas turbine power...


	Yes a lot of last mile stuff might be out, but the core
net and clouds not so much...

	Cell nets I'd suppose depends on the specific infrastructure,
but most of it does not seem that vulnerable to me...

	High altitude nuclear EMP is fairly steep rise time, I believe
CME EMP would be mostly large rather LF magnetic field jumping...

	Most any radio would help... except for satcom stuff... which
might not survive...
