Reporters sans frontières - The Internet under surveillance 2004: "Obstacles to the free flow of information online," reported by country for about 40 countries.  Also, in the article On a Filtered Internet, Things Are Not As They Seem, RSF reports that many countries have gone beyond blocking web sites:  "The past year has brought a rise of new filtering methods that, intentionally or by happenstance, are considerably more confusing. Try using Google in China : Most searches work fine.. But run a search on a controversial policy area, and Google will stop working for perhaps half an hour. ..

Still more subtle are the "modified mirrors" sometimes used in Uzbekistan. Rather than simply blocking access to sites of political dissenters, Uzbek authorities make copies of the controversial sites - then change the copies to undermine or weaken the unsanctioned positions. The key step : When Uzbek users request the controversial sites, they automatically receive the altered copies in place of the authentic originals. Experts might realize something is wrong, but this tampering is exceptionally difficult for ordinary users to notice or detect. "
