An advocacy group that helps internet users inside China bypass blocks on censored content says it is suffering a denial-of-service attack disrupting its operations.

US-subsidised Greatfire.org says the attack started two days ago and traffic is 2,500 times above normal. It has affected “mirror”, or duplicate, websites that it has set up via encrypted web services offered by companies such as Amazon.

Greatfire.org said the attack has interfered with visitors to sites including Boxun.com, which publicises allegations of corruption and human rights abuses inside China, German provider Deutsche Welle, and Google.

The statement from a co-founder of the group, who goes by the pseudonym Charlie Smith, said it’s not clear who is behind the attack, but it coincides with increased pressure on the organization over the last few months and public criticism from Chinese authorities.
