domain.com resolves, www.domain.com doesn't

I deployed a fresh ubuntu 10.04 and followed the LAMP guide in the library. I am able to access domain.com but www.domain.com times out. Here is my configuration:

DNS:

; example.com [125849]
$TTL 3600
@    IN  SOA ns1.linode.com. me.example.com. (
                    2010101729

                    3600 
                )

ErrorLog /srv/www/example.com/logs/error.log

CustomLog /srv/www/example.com/logs/access.log combined

The url in question is http://www.parkerault.com/

I followed the guide to the letter, so can anyone spot what I did wrong?

EDIT: using XX.XXX.XXX.XXX hostname.example.com hostname in /etc/hosts doesn't change the behavior.
