... and here's a (really ugly) bit of bash to allow you to check all of them:
for letter in `echo "abcdefghijklm" | grep -o .` ; do echo "Letter:
${letter}"; dig ns . @${letter}.root-servers.net | grep
b.root-servers.net | grep ; done

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.

Well something in the resolution path is changing the answer to
return the old  address which is why I suggested that there may
be a forwarder involved.  One should get a answer like this from
all of the root server addresses.  The exact ordering of the records
may differ.  If one doesn't then something on the path is modifying
the response.
