From guardian.co.uk:
Chinese internet users are rebelling against an internet crackdown brought in on the anniversary of the Tiananmen Square massacre.
Twenty years after the pro-democracy protests that claimed the lives of hundreds – or even thousands – of unarmed civilians in Beijing, a number of websites appear to be making a veiled protest at state censorship by referring to the date sarcastically as “Chinese Internet Maintenance Day“.
Earlier this week the government blocked access to a number of popular western websites, in what was widely seen as way of controlling access to information about the events at Tiananmen Square. Among the sites that were screened out were photo-sharing website Flickr, Microsoft’s Hotmail email service and the popular online messaging site Twitter.
