Paranoid ICANN opens another root server in China
ICANN has announced the creation of another root server instance in China, which definitely, DEFINITELY won’t let the Chinese government mess with the interwebs.
ICANN said this week that it’s opened an instance of the L-root that it manages in Shanghai.
It’s the third L-root in China but only the first outside of Beijing.
In a press release announcing the installation, which was carried out with technical support from CNNIC and Shanghai Telecom, ICANN decided to preemptively head off any concerns that putting an important piece of internet infrastructure in China comes with added security risk:
Contrary to common misconception, root servers do not control the Internet. The operation of an instance also does not provide any mechanism to alter content of the DNS. Any modification of root zone content will be mitigated by a part of the DNS protocol known as the DNS Security Extensions (DNSSEC) and if an instance fail to respond to a query, resolvers will ask the same question to another instance or root server.
It’s merely the latest of 168 L-root installations and 1,015 copies of the 13 logical root servers, which all use IP Anycast to more quickly serve DNS answers to their local users.
Given how big and populous China is, there are surprisingly few root server instances in the country, according to root-servers.org.
In addition to ICANN’s three boxes, Verisign’s J-root and Internet Systems Consortium’s F-root have three in Beijing and two in Hangzhou between them. The K, I and F roots each have one instance in Beijing.
That’s eight nodes in China proper, which has 800 million internet users. Cross the border into semi-autonomous Hong Kong, which has a population of under eight million people, and there are nine root instances.
The city of Bucharest, Romania (pop. 1.8 million) has the same number of root instances as China.
