There was something related, or most probably the same problem
last year with the resolvers running on the bbc.co.uk domain and
some others, check here:

"incorrect NXDOMAIN response from DNS server"

For the over 2 years now that I have been using an IPv6 enabled IE
I haven't come across that problem much times though, at least not
that I have noticed. But then again I am probably not a typical
top500 website crawler :)
