  My experience with the dslreports forums is that they can be useful
to get one started looking for something, but ultimately distribute
more misinformation than your average Iraqi information minister...

  The only reason I can think of to block UDP 53 would be some kind of
widespread DDoS attack against the root or GTLD servers, and even
then, that would likely be a temporary measure.  (The root's briefly
blocked ping for a little due to that reason.)
