--FILE-- View of the new headquarters and head office of Baidu in the Beijing Shangdi Information Industry Base in Haidian District in Beijing, China, December 16, 2009. Top Chinese search engine Baidu.com has sued its U.S. domain registrar over a hack that took down the Web site, alleging negligence by the U.S. company, Baidu said Wednesday (January 20, 2010). Users had trouble accessing Baidu.com for several hours last week after the companys domain name server in the U.S. was tampered with. The Iranian Cyber Army, the same group that took down Twitter last month, also appeared to be behind the attack on Baidu. Baidus lawsuit, filed in a court in New York, seeks related damages and alleges gross negligence by Register.com led to the service disruption, Baidu said in a statement. Baidu only said Baidu.com was hit by the outage, and that mirror site Baidu.com.cn had not been affected. Domain service providers including Register.com provide the setup needed to take Internet users to the correct Web site when they type a domain name like Baidu.com.
