Whistleblowing organisation WikiLeaks has moved its website to Switzerland as it struggled to remain open in the face of official and corporate moves to cut its access to the internet.
And there was speculation that an arrest of the site's founder Julian Assange might be imminent, after Swedish authorities refiled an international warrant with additional information requested by the Metropolitan Police.
The 39-year-old Australian former computer hacker, who is understood to be in the UK, answered questions on The Guardian's website, and hailed as "an unparalleled hero" the soldier suspected of passing 250,000 secret US diplomatic papers to WikiLeaks.
Mr Assange praised US Army intelligence analyst Bradley Manning, 23, without confirming he was the source of the leaks which have deeply embarrassed Washington and its allies.
The latest tranche of confidential documents to appear on the website included cables from the US embassy in Afghanistan reporting criticisms of Britain's military operations in the country by President Hamid Karzai and a top Nato commander.
And cables from the London embassy showed that former US ambassador Robert Tuttle had written Gordon Brown's premiership off as "abysmal" within a year of him becoming Prime Minister.
The website moved to the Swiss address wikileaks.ch after the American company providing its domain name, EveryDNS.net, cut off service because cyber attacks were threatening the rest of its network.
WikiLeaks had turned to EveryDNS and servers in Europe after Amazon stopped hosting the site on Thursday. Meanwhile, reports suggested that authorities in Paris were trying to ban French servers from hosting its database of leaked information.
Mr Assange said WikiLeaks' activities had been dictated since April by "the moves of abusive elements of the United States Government against us".
He added: "The threats against our lives are a matter of public record, however, we are taking the appropriate precautions to the degree that we are able when dealing with a superpower."
