(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. 
 
 CNN's Melissa Hassett and Jason Kessler contributed to this story. ||||| After getting dropped by Amazon's web hosting service yesterday, Wikileak was booted today from its Domain Name Service provider. Now Wikileaks is down again, and effectively homeless. 
 
 In a statement, EveryDNS says they were forced to terminate their relationship with Wikileaks to protect stability for other customers: 
 
 ...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. Thus, last night, at approximately 10PM EST, December 1, 2010 a 24 hour termination notification email was sent to the email address associated with the wikileaks.org account. 
 
 It adds, "Any downtime of the wikileaks.org website has resulted from its failure to use another hosted DNS service provider." A site like Wikileaks needs a DNS service provider to keep its domain name up and running. With non-functioning domain name, Wikileaks now risks becoming "a digital refugee," as tech writer Evgeny Morozov tweets. 
 
 Regardless of the motives behind EveryDNS' decision, we should keep in mind it's a free service... maybe Wikileaks should have used some of their hundreds of thousands of dollars in donations to get a backup? Now Julian Assange will have to release all the cables in Facebook status updates. ||||| Amazon has pulled the plug on WikiLeaks, the site that earlier this week began releasing a mammoth collection of confidential U.S. State Department diplomatic cables. 
 
 "WikiLeaks servers at Amazon ousted," said WikiLeaks around 3 p.m. Eastern time on its Twitter account. "Free speech the land of the free ... fine our $ are now spent to employ people in Europe." 
 
 According to reverse IP traces run by Computerworld, WikiLeaks is now hosted by a Swedish firm, Bahnhof Internet AB, which is headquartered in Uppsala, a city approximately 44 miles north of Stockholm. 
 
 As of 3:30 p.m. Eastern time, the primary WikiLeaks site was available to Computerworld staffers in the U.S., but some attempts at reaching the URL failed. 
 
 A subsidiary site, Cablegate.wikileaks.org, where the organization has published the full text of more than 500 of the over 250,000 cables in its possession, was also operational. That site had also been shifted to Bahnhof Internet's servers. 
 
 Earlier in the week, the Cablegate site had been hosted by a French firm. 
 
 WikiLeaks moved to Amazon's hosting service on Monday, apparently as a defensive tactic to avoid or mitigate aggressive denial-of-service (DoS) attacks that took the site offline for several hours that day and then hammered it again yesterday. 
 
 According to Craig Labovitz, chief scientist at Arbor Networks, the DoS attacks continued throughout Wednesday morning. 
 
 Amazon's hosting terms of service allow it to yank a site off its service without cause. 
 
 "[Amazon Web Services] reserves the right to refuse service, terminate accounts, remove or edit content in its sole discretion," the terms state. 
 
 Another clause may have also been invoked. "You represent and warrant that you own or otherwise control all of the rights to the content," Amazon's terms continue, "[and] that ... the content you supply ... will not cause injury to any person or entity." 
 
 On Monday, Secretary of State Hillary Rodham Clinton said, "Whatever are the motives in disseminating these documents, it is clear that releasing them poses real risks to real people, and often to the very people who have dedicated their own lives to protecting others." 
 
 Amazon did not reply to queries on Monday about its hosting of WikiLeaks, nor did it respond to follow-up questions today.

– WikiLeaks' US domain host terminated its account last night, making the website inaccessible for the third time in a week ... but it's already back online. EveryDNS, which had hosted the wikileaks.org domain name for 4 years, said the site has become the target of multiple denial-of-service attacks, threatening EveryDNS's infrastructure, Gawker reports. But hours after being booted, WikiLeaks announced a move to a company in Switzerland and tweeted its new URL, CNN reports. The move by EveryDNS—a subsidiary of New Hampshire-based firm Dynamic Network Services—meant WikiLeaks was briefly down, but not out, ZDNet notes. While typing wikileaks.org into a browser didn't take users to the site, much of its content could still be reached via IP addresses, and its leaked diplomatic cables have been widely distributed through file-sharing sites.
