Herdict Web is a crowdsourcing site that gathers user-generated reports about Web site accessibility (and filtering) from around the world to draw a real-time image of which sites are accessible and inaccessible, where, and for how long.¬† Users interested in discovering where Twitter is currently blocked, for example, or what news sites are blocked in Iran, can easily find out using Herdict’s Explore function.¬† Although an inaccessible report is not a guarantee of government filtering (many users in the United States, for example, might be reporting from behind workplace filtering), a great number of reports on an ISP in a given country is a good indicator.¬† The Herdict Discussion Board allows users to dig deeper to discover more information about an instance of inaccessibility.

Today, Herdict Web has launched new interfaces in Persian and Russian.  The Persian site is particularly relevant; the Iranian government is said to block nearly 3 million Web sites.  Herdict has already received over 10,000 visits from Iran since its launch in 2009.

The site is also available in English, Chinese, and Arabic.
