>Declan,

>Professor Jonathan Zittrain and I are studying Internet filtering in
>countries worldwide, including restrictions on Web access in China.  As in
>our prior testing of Saudi Arabia [1], there has been no publicly available
>master list of blocked sites.  To assemble something approaching such a
>list, we have found ways to remotely test "twenty questions" style, asking
>about thousands of individual URLs, whether based upon a domain name or an
>IP address.
>
>To help us broaden the number and types of pages tested and to provide the
>general public a means of finding out whether particular pages of interest
>are filtered, we have created a web page at which users can see whether a
>given site is likely accessible from China, and in doing so suggest that we
>test that site going forwards.  We'll track all requests and retest them
>over time, reporting the results in our forthcoming report about Internet
>filtering in China.  We're eager to see whether such "open source research"
>will end up finding a substantial number of blocked sites that, despite our
>best efforts, we neglected to think of asking about ourselves.
