This sounds like the most likely culprit to me. Gotta love the way our
ISP's enjoy feeding us whatever advertising/etc... that they feel they
can get away with.
One solution to this issue would be to run your own DNS server and have
that query the root servers directly. I started doing this several
months ago because my ISP's DNS servers were rather slow and non-responsive.
