WikiLeaks said Friday that it had been taken offline by its US-based domain name hosting firm provider following allegations of massive cyber attacks on the site.

"WikiLeaks.org domain killed by US everydns.net after claimed mass attacks," a message on the whistleblowing website's Twitter feed said.

"KEEP US STRONG," the message continued, inserting the link to a donations website.

A statement on the everydns.net website said the company provided domain name services (DNS) to WikiLeaks until 0300 GMT Friday, when such services were terminated.

"As with other users of the EveryDNS.net network, this service was provided for free. The termination of services was effected pursuant to, and in accordance with, the EveryDNS.net Acceptable Use Policy," the statement said.

"The interference at issues arises from the fact that wikileaks.org has become the target of multiple distributed denial of service (DDOS) attacks.

"These attacks have, and future attacks would, threaten the stability of the EveryDNS.net infrastructure, which enables access to almost 500,000 other websites."
