Chinese citizens are facing an even tougher internet firewall as the ruling Communist party tries to enforce silence and amnesia on a seething nation striving to grieve and commemorate the 25th anniversary of the Tiananmen Square massacre.

The firewall, which blocks many sites including Twitter and Facebook, now blocks all of Google’s services from search and Google maps to the more innocuous calendar or slides apps.

The block was revealed by internet access activist group GreatFire, which published a report into the Google block earlier this week.
