Learn more about the situation and context, test the exclusions for yourself, and submit further sites suspected to be excluded. More below:

This work continues our study of Internet filtering in countries worldwide. To date, this work has focused on filtering in the context of affirmative actions by governments to restrict the sites viewed by their respective users. However, we are also interested in requests or demands to private parties that they assist in preventing particular citizens' exposure to locally unwanted or illicit data or activities. Search engines are increasingly the targets of such requests, and in our recent work we have attempted to begin to document some of the specific sites filtered -- reluctantly, we gather! -- by the French and German versions of Google.

As in our prior testing of Internet filtering China and Saudi Arabia, there exists 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 web servers.

To help us broaden the number and types of servers tested and to provide the general public a means of finding out whether particular pages of interest are filtered, we have created a web site at which users can see whether a given site is excluded from French or German search results. We'll track all requests and report the results in our forthcoming report about exclusions from Google. 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 did not know about and therefore ask about ourselves.

We have also prepared a listing of 100+ sites filtered in France and/or Germany, as well as screen-shots and a system by which interested users can confirm, using their own browsers and their own Internet connections, the reported divergence between results on google.com versus google.fr and google.de.
