Google Inc services were once again being disrupted in China on Friday after a brief respite on Thursday, users and an anti-censorship group reported, continuing more than a month of severe disruption. Features such as Google's search, maps, online advertising services and e-mail client have been rendered almost inaccessible for users in China. The Google disruption began in the run-up to the 25th anniversary of the government's bloody crackdown on pro-democracy demonstrators around Beijing's Tiananmen Square. China maintains tight control over the Internet, nipping in the bud any signs of dissent or challenges to the ruling Communist Party's leadership.
