Another odd political item. George Bush's campaign Web site has cut off access for people outside the United States (and seemingly Canada). They're not explaining why. It doesn't make much sense, unless they were starting to see denial of service attacks originating overseas.
If this is the case, the move might start to make sense. The campaigns are using the Net as a powerful grassroots mobilization tool, with volunteers all over the country tapping into phone banking and other databases. A concerted attack on the sites servers could play havoc with those resources at the last minute, unless there are good security measures in place.
