WikiLeaks back after Amazon pulls the plug

WikiLeaks is back online, after Amazon stopped hosting the whistle-blowing website which earlier this week posted thousands of secret US diplomatic cables.

Amazon pulled the plug on the site under pressure from Senator Joe Lieberman, chairman of the Homeland Security and Governmental Affairs Committee, whose staff questioned Amazon over its relationship with WikiLeaks.

Lieberman announced in a statement:

"This morning Amazon informed my staff that it has ceased to host the Wikileaks website. I wish that Amazon had taken this action earlier based on WikiLeaks' previous publication of classified material."

WikiLeaks had switched to Amazon's self-service, cloud-based hosting as a security precaution, after an attack on Sunday by self-styled 'hacktivist for good' The Jester brought its servers down.

After disappearing yesterday, the site is now back up, having returned to the servers of its previous host, Bahnhof, in Sweden.

The site announced the switch in a post on Twitter: "WikiLeaks servers at Amazon ousted. Free speech the land of the free--fine our $ are now spent to employ people in Europe."

Shortly afterwards, the site added: "If Amazon are so uncomfortable with the first amendment, they should get out of the business of selling books."

This morning the site was again sparking controversy with its publication of confidential US cables concerning Russia.

The latest leaks describe prime minister Vladimir Putin's regime as a "virtual mafia state", with bribery functioning "like a personal taxation system".

In an interview with US talkshow host Larry King, Putin called the cables "slanderous".
