Any chance you're running a caching-only nameserver locally and you got 
a bad answer once and are caching it?

I deleted too many of the early messages by accident, and lost the big 
picture here, but a caching nameserver that's doing negative caching can 
be quite confusing when you're hunting down a problem.
