I saw this problem late last night too.  The problem was "downstream" 
in the CNAME chain.  I was able to access IMDB by using 
us.dd.imdb.com (http://us.dd.imdb.com) while the www.imdb.com address 
was (in some sense of the word) "broken."  My local recursor got a 
SERVFAIL for www.imdb.com and inserted a redirection page for it. 
Using dig +trace at the time I could work my way around the issue.  I 
bet the recursor got most of the way there but couldn't get the A 
record or something.

As it was very late for me, I didn't try to "debug" it.  Just had a 
burning question about I movie I had just seen. ;)
