Access Denied: The Practice and Policy of Global Internet Filtering challenges the long-standing assumption that the internet is an unfettered space where citizens from around the world can freely communicate and mobilise. In fact, the book makes it clear that the scope, scale and sophistication of net censorship are growing.

“There’s been a conventional wisdom or myth that the internet was immune from state regulation,” says Ronald Deibert, one of the book’s editors.

“What we’re finding is that states that were taking a hands-off approach to the internet for many years are now finding ways to intervene at key internet choke points, and block access to information.”

Mr. Deibert heads The Citizen Lab at the University of Toronto. The Lab, along with Harvard Law School, the University of Cambridge, and Oxford University, has spent the last five years testing internet access in some 40 countries.
