I suspect that the Internet would die naturally as sections broke down.
I winder how ling the phone network would last. Don't think we'll get
the ray bradbury type secenarion in his Martian Chronicles of phones
ringing all over the planet but I expect there would be some freak bits
surviving for some time.

A popint to ponder, as the new generation are internet and texting
orientated I wonder if that would be how they would conceive of
reestablishing communication ie reinventing letters and a postal
service but this time one where letters were delivered to central
mailbox depositories and collected from them. Perhaps the earliest form
of fax might be the next stage used to communicate at a distance

eg. http://www.hffax.de/html/hauptteil_faxhistory.htm

Then some form of jellygraph duplication could multiply copies for
distribution locally. Who knows we might even see the reestablishment
of the learned society next.
