Do you realize that most internet connections are made by computers.YOU CANT DESTROY THE INTERNET WITHOUT DESTRYOYING THE COMPUTER FIRST.Duh!!
While that makes sense, it's like saying -
"Just because my phone broke there's no global communication"
If the computer had crashed, yes your
connection to the internet has been destroyed, but has the internet itself been destroyed? No.
While people can say that the internet is housed in personal servers accross the globe, that's not entirely true either. Those are just ways to add to the internet, Bonus Packs for the main game so-to-say. The internet has been and will always be a government-controlled global communications system.
So, this said, then theoreticly, a direct attack on the goverment controlled main server which houses the programming for the internet, would be more wise, for if done correctly, not only could you have the same disasterous effects, at the same time, the common-folk would only think their service provider was down. They would only figure out the connection was out globaly if either -
A) The government admitted their security backfired and cause mass-panic doing so
B) They spend weeks trying to fix their connection, randomly bring it up to a friend, they ask around, and it turns out everybody else has the same problem.
Giving the culprit plenty of time to escape, because the government loves keeping secrets and not causing mass-panic.
*wonders why he said this*
