After DNS Problem, Chinese Root Server Is Shut Down

Robert McMillan writes on PC World:

A China-based root DNS server associated with networking problems in Chile and the U.S. has been disconnected from the Internet.

The action by the server's operator, Netnod, appears to have resolved a problem that was causing some Internet sites to be inadvertently censored by a system set up in the People's Republic of China.

On Wednesday, operators at NIC Chile noticed that several ISPs (Internet service providers) were providing faulty DNS information, apparently derived from China. China uses the DNS system to enforce Internet censorship on its so-called Great Firewall of China, and the ISPs were using this incorrect DNS information.

That meant that users of the network trying to visit Facebook, Twitter and YouTube were directed to Chinese computers instead.

In Chile, ISPs VTR, Telmex and several others -- all of them customers of upstream provider Global Crossing -- were affected, NIC Chile said in a statement on Friday. The problem, first publicly reported on Wednesday, appears to have persisted for a few days before it was made public, the statement says.
