The authors are studying Internet filtering in countries worldwide, and current investigations focus on restrictions on web access in China. Using a web-based system to test web filtering in China, the authors previously determined and confirmed that Google was inaccessible from at least one testing location in China; initially, in testing beginning August 29, a request for Google led to the error “host not found,” consistent with requests for other inaccessible or blocked sites. However, using related methods, the authors have now confirmed and documented reports that Chinese Internet access currently provides pages other than the ordinary Google home page in response to requests for google.com; such behavior is believed to have begun on September 8. The screen shots in this article document six instances of this replacement. Full article.
Documentation of Internet Filtering in Saudi Arabia with Jonathan Zittrain
Jonathan Zittrain and Benjamin Edelman. “Documentation of Internet Filtering in Saudi Arabia.” September 12, 2002.
Abstract: The authors connected to the Internet through proxy servers in Saudi Arabia and attempted to access approximately 60,000 Web pages as a means of empirically determining the scope and pervasiveness of Internet filtering there. Saudi-installed filtering systems prevented access to certain requested Web pages; the authors tracked 2,038 blocked pages. Such pages contained information about religion, health, education, reference, humor, and entertainment. The authors conclude (1) that the Saudi government maintains an active interest in filtering non-sexually explicit Web content for users within the Kingdom; (2) that substantial amounts of non-sexually explicit Web content is in fact effectively inaccessible to most Saudi Arabians; and (3) that much of this content consists of sites that are popular elsewhere in the world.
Expert Report and Appendices for Multnomah County Public Library et al., vs. United States of America, et al.
I had the honor of testifying, in writing and orally, in Multnomah County Public Library et al., vs. United States of America, et al., an ACLU challenge to the Children’s Internet Protection Act. My expert report, rebuttal report, and supplemental report include documentation of specific pages wrongly blocked by adult filters.
Real-Time Testing of Internet Filtering in China with Jonathan Zittrain
My Real-Time Testing of Internet Filtering in China tool (no longer available) let users check what web sites China was blocking. All test results were logged for research, extending Internet Filtering in China (IEEE Internet Computing 2003).
