"Surfers outside the US have been unable to visit the official re-election site of President George W Bush.
people living outside the US trying to look at the site simply got a message saying "access denied"."
The blocking does not appear to be due to an attack by vandals or malicious hackers, but as a result of a policy decision by the Bush camp.
That just seems a little strange. One possible argument is that:
"...the blocking decision was taken to cut costs, and traffic, in the run-up to the election on 2 November.
He said the site may see no reason to distribute content to people who will not be voting next week.
Managing traffic could also be a good way to ensure that the site stays working in the closing days of the election campaign. "
Nevertheless, I would speculate that it was the almost imminent DoS attacks in the days leading up to the Nov. 2nd vote that Bush staff decided to pre-empt. The last sentence of the quote alludes to that possibility as well.
