Anonymous, a hactivists’ conglomeration which is opposing the internet censorship has claimed to have taken down the Mahanagar Telephone Nigam Limited (MTNL) website using the technique of Distributed Denial of Service (DDoS) attack on Wednesday.

A posting by Anonymous on its webpage claimed that it hit the website ‘mtnl.net.in’ with a massive DDoS attack. Attempts to log onto the website returned pages with error messages saying the requested URL could not be retrieved.

Anonymous has called for non-violent protests across several cities in India on June 9 to protest against what it alleges as ‘censorship’ of the internet. It accused the department of telecom of instructing the Internet Service Providers (ISPs) to block file-sharing websites unilaterally, while the courts had ordered blocking of certain websites.

The group had earlier targeted websites of the government and also of corporates and political parties which they accused of supporting the ‘illegal’ ban.

The Anonymous group has called upon netizens to wear ‘Guy Fawkes’ masks, which have become synonymous with Occupy Wall Street protests, during the June 9 protests.
