The BBC, using data collected by Netcraft, reports that since Monday October 25th 2004, the official website of the Bush-Cheney campaign website (www.georgewbush.com) has been restricted to Internet users located in the United States. Subsequent reports indicate that this filtering was implemented for unspecified security reasons.

Geolocation filtering refers to a situation when Internet content providers, such as websites, restrict or modify the content delivered to users based on geographical regions. This type of geographically-targeted filtering uses geolocation technology to determine an Internet user's geographic origin by looking up the requesting users' numerical Internet protocol (IP) address in databases that associate IP addresses with particular countries. Advanced geolocatation databases can also match regions and cities with specific IP addresses.
