WikiLeaks' main website could not be accessed on Friday through its domain name after a subsidiary of Dynamic Network Services terminated its domain name service.

Dynamic Network Services' subsidiary,, terminated the domain name because repeated DDOS (Distributed Denial of Service) attacks against WikiLeaks "have, and future attacks would, threaten the stability of the infrastructure, which enables access to almost 500,000 other websites," it said on its website. said it notified WikiLeaks on Thursday by email, Twitter and the chat function available through the website that its domain name service would be terminated in 24-hours.

"Any downtime of the website has resulted from its failure to use another hosted DNS service provider," said.

WikiLeaks put out a note on Twitter saying, "WikiLeaks,org domain killed by US after claimed mass attacks," and implored supporters to keep WikiLeaks strong with continued donations.

The WikiLeaks comment appeared at odds with an earlier WikiLeaks Twitter post saying that DDOS attacks against its servers reached 10 Gigabits per second on Nov. 30. Amazon Web Services also confirmed the DDOS attacks, saying in a blog posting that, "There were indeed large-scale DDOS attacks, but they were successfully defended against."

The domain name service termination comes just days after Amazon Web Services stopped hosting WikiLeaks on its servers for breaking user rules saying that websites must use their own content and not carry data that might injure others. The US Homeland Security and Governmental Affairs Committee, chaired by Senator Joe Lieberman, had also asked Amazon to stop hosting the controversial website.

WikiLeaks has come under fire for publishing classified US documents, including videos and documents from the wars in Iraq and Afghanistan as well as sensitive cables sent between US embassies and the US State Department. WikiLeaks continues to post the cables.

Dynamic Network Services is a US company based in Manchester, New Hampshire. Its subsidiary said all of its systems were functioning normally.
