Will China's Great Firewall backfire?
Google may have rolled out its cloud-storage Google Drive last week, but some 500 million internet users may never have a chance to try it out - those in China.
Having hit the country's so-called Great Firewall, Google Drive has joined a host of other services banned in the communist nation, such as YouTube, Google+, Twitter, Dropbox, Facebook and Foursquare.
When the firm checked for technical issues on its side, it found none, a Google spokesman told the BBC. "If people are unable to access Google Drive in China... it's an issue to take up with the Chinese authorities," he said. The restriction does indeed seem to come from Beijing, but it is not a surprise, say analysts.
