Good piece by Ars Technica’s Nate Anderson explaining how the U.S. government was able to take down Megaupload, a company theoretically headquartered in Hong Kong: Megaupload wasn’t just some Hong Kong enterprise that “happened” to be used by US residents. The site had leased more than 1,000 servers in North America alone; 525 were at Carpathia Hosting and were located in Virginia. Between 2007 and 2010, Carpathia received $13 million from Megaupload. (Cogent Communications in the US supplied a few additional US servers and bandwidth.)
