Punching Holes in Internet Walls On one side are the governments that have restricted Web access. In some countries, like Singapore, most of the banned sites are pornographic. Many of these countries also block the sites of political dissidents, but the censorship may be much broader than that. In the Middle East, for example, anti- Islamic sites and gay sites are often off- limits. In China, the prohibition includes the sites of Western publications, human rights organizations and Falun Gong, the banned spiritual movement. And Saudi Arabia also blocks sites for financial reasons: its ban on Internet telephony favors its own state-run telephone monopoly. Countering such government restrictions are services, some free, that are provided by companies like SafeWeb (www.safeweb.com), Anonymizer (www.anonymizer.com), SilentSurf.com (www.silentsurf.com) and the Cloak (www.the-cloak.com). During the conflict in Kosovo in 1999, for example, Anonymizer, based in San Diego, set up free services so that Kosovo residents could communicate with less fear. http://www.nytimes.com/2001/04/26/technology/26SAFE.html?pagewanted=all
