Chinese activist site Greatfire is under a sustained Distributed Denial-of-Service (DDoS) attack that is racking up $30,000 a day in server costs.
The website masks internet traffic from websites including Facebook and Google, so it can be seen in China, and does so using cloudy servers.
Website administrator Charlie Smith said the DDoS is delivering 2.6 billion requests an hour, saying that the attack is aggressive and is an exhibition of censorship by brute force. “Attackers resort to tactics like this when they are left with no other options,” he said.
The DDoS is a 2,500 increase on normal traffic levels and is slamming all GreatFire website mirrors of websites blocked on the mainland.
