Documentation of Internet Filtering Worldwide by Jonathan Zittrain and Benjamin Edelman - A variety of organizations, institutions, companies, and countries seek to restrict Internet access from within their premises and territories. For example, companies may seek to improve employee productivity by restricting access to leisure sites; libraries and schools may seek to avoid exposing children to sexually-explicit content, or be required to do so; countries may seek to control the information received by their citizens generally. Common among nearly all these applications is the public unavailability of the filtering lists — that, by the design of filtering systems, users cannot and do not know the set of specific sites blocked. In some cases users might ask for a specific site and be told of its unavailability due to filtering, but in other cases such unavailability may be conflated with unremarkable network blockages — a Web site might be unreachable for any number of reasons, and the failure to view it at a particular moment cannot reliability be attributed to active filtering. With this project we seek to document and analyze a large number of Web pages blocked by various types of filtering regimes, and ultimately create a distributed tool enabling Internet users worldwide to gather and relay such data from their respective locations on the Internet.
