(CNN) -- A U.S.-based domain name provider shut down WikiLeaks early Friday, but the controversial website announced hours later that it had employed a company in Switzerland and was back up.

"WikiLeaks moves to Switzerland," the company said on its Twitter page about 4 a.m. ET.

The tweet also provided WikiLeaks' new web address.

U.S.-based domain provider EveryDNS.net shut down WikiLeaks' old web address early Friday.

The company announced that it had to cut its relationship with WikiLeaks because the site had received multiple cyber attacks.

"EveryDNS.net provided domain name system (DNS) services to the wikileaks.org domain name until 10 p.m. ET, December 2, 2010, when such services were terminated," the U.S.-based company posted on its website.

"More specifically, the services were terminated for violation of the provision which states that 'Member shall not interfere with another Member's use and enjoyment of the Service or another entity's use and enjoyment of similar services.'

The company said Wikileaks.org has become the target of multiple cyber 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."

WikiLeaks lamented the shutdown on its official Twitter page early Friday.

"WikiLeaks.org domain killed by US everydns.net after claimed mass attacks KEEP US STRONG," the company posted early Friday morning.

Amazon also kicked the site off its servers.
