China has begun using an “offensive system” able to disrupt access to websites outside its borders, according to researchers at the University of Toronto.

The deployment of this system represents a “significant escalation in state-level information control,” the university’s Citizen Lab said in a report posted to its website Friday. This system, dubbed the “Great Cannon” by the researchers, was used in recent attacks on GitHub Inc. and servers used by GreatFire.org, according to the report.
