fixed?
Most probably, you are running into delays because your browser queries 
websites for an IPv6 address before trying an IPv4 address.  
Reportedly, many ad-sites use broken nameservers which botch IPv6 
queries, causing the delay.  The problem lies on their end, not yours, 
but disabling IPv6 or using a proxy server like Squid will probably 
remove the delays.

Most of that is true.  However, I found it to be a problem with firefox
specifically - in that firefox waits for the 75 second timeout.  Forced
me to switch to opera :)

It looks like it will be fixed in the next version of mozilla, though:
http://bugzilla.mozilla.org/show_bug.cgi?id=68796

The quickest workaround is to add 
::0 ad.doubleclick.com
::0 ad.doubleclick.net
to /etc/hosts (not a bad thing to keep in there, really).
