U.S. officials at the Pentagon and State Department denied Friday knowing of any efforts to take down the WikiLeaks website or asking companies to do so.
The site's efforts to publish 250,000 diplomatic cables has been hampered by denial-of-service attacks, ejection from its server host and cancellation of its name by its American domain name provider. Each time WikiLeaks has worked out other arrangements to bring the site back online.
In written answers to readers' questions posted on the website of the British newspaper The Guardian, WikiLeaks' founder Julian Assange alleged "abusive elements of the United States government" were behind the site's technical problems. A State Department spokesman disputed that the U.S. government was involved.
"I am not aware of any conversations by the United States government with either any internet host here or any government over there at this point," said spokesman P.J. Crowley.
A Defense Department official also denied causing the technical problems slowing the WikiLeaks release of secret U.S. government documents.
