A Distributed Denial of Service (DDoS) attack hit .cn websites on 25 August, meaning many “were either inaccessible or extremely slow, including the popular Twitter-like Sina Weibo, Amazon.cn, and the Bank of China,” according to a Tech In Asia report.
Following the attack, the China Internet Network Information Center (CNNIC) said service is being resumed slowly.
Tech In Asia continued, “about 30 minutes after midnight on Sunday, the attacks crippled the registry for more than 13 hours until 2 p.m.. Then, just two hours later at around 4 p.m., another wave of attacks struck. CNNIC did not specify where the attacks originated from, but it did say it was the largest denial of service attack it’s ever underwent. As of the latest announcement, the registry is still recovering.”
