[Gllug] so after the DNS - Attack

Well, I've heard persistent rumours of successful attacks on and
takeovers of major routers: I suppose a sufficiently determined attacker
could penetrate a large percentage of the net's routers, lurk there,
then take them all down at once.

But that would shatter the networking layer rather than merely taking
down the naming service. I can't see any way to take that down that
doesn't also take down lower layers (e.g. global thermonuclear war with
EMP-enhanced orbital nukes, that'd do it: I doubt many of the root
servers are in Faraday cages with their power supplies).
