Odd, I'm seeing it now. Couldn't see it for 20-30 minutes.

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. ;)
