Patched BIND is an elegant solution (Score 4, Informative)

I just installed the patched BIND 9.2.x for NodeWorks so it could keep finding dead links for customer sites. Without this kind of technical solution, I would have had to check for redirects to the sitefinder site, and added specific logic to mark the response as invalid since it would otherwise return a valid 200 HTTP response code.

The new feature just needed this bit added to named.conf to get it working:

zone "com" {
type delegation-only;
};
zone "net" {
type delegation-only;
};

When its running, it will put message like this to /var/log/messages so you can see it working!

Its really amazing that the open source community can turn around a patch like this within hours of the initial problem being reported! Not only that, but the implementation is clean and technically elegant.
