Internets under attack

So the internets were placed under sustained attack over the last couple of days and it was extremely lucky that the tubes didn't crack under the pressure. Well that's sort of interesting, but to me the far more interesting fact is that 13 computers control the whole internet. It just doesn't make any sense, one of the key things about the net is that despite individual sections of the net going down other portions should still be able to talk to each other. I dunno people if this is all that's stopping the aliens from seizing world domination then we better start working on installing norton antivirus 1993 on all these computers to prevent attacks.
