Is there a way to track those attacks? Do they come from random zombie boxes, or maybe the IPs are from somewhere in Virginia?
I'd bet there are some Governments involved as well as individuals who dislike Wikileaks.
Since the DoS attack comes from so many places, it's very difficult to trace.
It doesn't take a genius to know DDOS'ing isn't going to accomplish anything of significance, basically you just have to be paying a fraction of attention.
