The French government has moved to ban WikiLeaks from French servers, part of a series of moves threatening the group's presence on the internet.
Industry minister Eric Besson said it is "unacceptable" for French servers to host the site, which "violates the secret of diplomatic relations and puts people protected by diplomatic secret in danger".
The American company which hosted the wikileaks.org site stopped late on Thursday after cyber attacks threatened the rest of its network.
WikiLeaks responded by moving to a Swiss domain name, wikileaks.ch - and calling on activists for support.
Two companies host the Swiss domain name, one of which is in France.
