Just got on this thing (perhaps very belatedly) - root server trouble?

Nice dodge. But you do then admit to having recursion available on
your "new improved r00t n at m3s3rv3rs" for several months, until someone
else pointed it out to you?
"They did the same thing a while back!" isn't an acceptable answer. (I
don't even think it's true. I haven't seen a recursive query answered
via a root nameserver since I started actively doing DNS administration
over a year ago.) Even if that is so, you shouldn't have made the same
mistake, especially *after* the operators of the IANA root servers
corrected the misconfiguration.

I haven't seen any problems because of these supposed "service-affecting
issues". Perhaps you should check the quality of your network connectivity?

The code's fine; it just appears you don't know how to configure it correctly.
Try reading the BIND Operations Guide (BOG) next time; it says explicitly
that the root nameservers should run with "options no-recursion".
