How China's Web Traffic Wound Up In Wyoming

Half a billion Internet users in China were blocked from the Internet for nearly eight hours on Tuesday when China's vast "firewall," or censorship technologies, accidentally routed most of the country's web traffic to an Internet address registered to a company in Cheyenne, Wyoming.
