The whistle blower site shifted to Amazon after its servers in Sweden were hacked hours before the latest release of classified documents related to U.S. State Department’s internal communications on Sunday.

WikiLeaks said that it is now being hosted by servers in Europe.

WikiLeaks has criticized Amazon for denying services to it. It said on twitter, “If Amazon was so uncomfortable with the first amendment (of the U.S. Constitution), they should get out of the business of selling books.”

The hackers are using social networking sites like Facebook and Twitter to coordinate their efforts, thereby dragging these companies into the fray.
