Anywho how long do you really think it would take for all the DNS servers to either mover out of the states or be replaced (ied say days)
One word: wrong.
The IP is *NOT* retrieved from the site. When you request a webpage (e.g. tieupgames.net) a request for name solution is sent to your DNS (Dynamic Name Server). That server returns the IP adress of that site...and NOW the data transfer can start.
However, your local DNS server does *not* know the IP for every site. But he sends down your name solution request further in the DNS hierarchy. The top layer of the hierarchy are the root DNS servers (actually, these are not single servers, but server farms, but logically they act as one server). When they fail, you usually wont get a DNS solution- ergo, your program (be it a browser or ping) won't know the IP adress to look at.
As of now, there are 13 Root DNS server- 7 of which are US based. So, theoretically, with enough preparation time...it would be easy to "switch the light out" within seconds (or at least hamper the system enough that the remaining servers don't work properly anymore).
This vunerability has been a long time criticism about the DNS network (and thereby the part of the internet most people use, the www) and one should stop making oneselves illusions about that.
Sorry for the technical rant, but I want to dispel some of the wrong "knowledge" around here.
