China’s national DNS system was hit by one of the largest Distributed Denial of Service (DDoS) ever which took out thousands of .cn domains for almost two hours on Sunday.

According to a message posted on China Internet Network Information Center (CNNIC), the attack was noticed at around 2 in the morning and went on till 4 and noted that the access to multiple sites was affected and that the access was being gradually restored. CNNIC has apologized for the disruption in service and said that it was working on improving its service capabilities.

It seems that the attack was specifically targeted at .CN registry, which was shut down for a couple of hours, stated CloudFlare notes The Wall Street Journal. Despite the shut down the access to .cn domains wasn’t completely shut as service providers would have had a copy of the records which would have served users for the time being.

In an emailed statement to the WSJ, CloudFlare CEO Executive Matthew Prince stated that the company witnessed over 30 per cent fall in traffic for thousands of Chinese domains during the attack hours. He also stated that the attack may have been orchestrated by a single individual rather than a team.

Access to .cn domains has been completely restored today as users in china are reporting through several forums that they are able to access affected sites smoothly without any issues.

The attack on China is somewhat surprising as recent stats indicate that the walled country is still the biggest source of DDoS attacks – over 33 per cent of the global DDoS attacks.
