China hit by biggest cyber attack

China has been hit by the "largest ever" attack on its Internet structure, crashing the country's .cn servers, according to a government-linked agency.
The national domain name resolution service came under a distributed denial of service (DDoS) attack for around two hours early on Sunday, the China Internet Network Information Centre (CNNIC) said in a statement.
Domain name resolution is a key part of how the Internet works, converting a website name into a set of digits -- the IP address -- that computers can recognise. The service in China focuses on websites with the .cn extension.
