I click on Test Now and I get:

Not Found
The requested URL /tools/vu800113.php was not found on this server.
Apache/2.2.9 (Debian) mod_python/3.3.1 Python/2.5.2 mod_perl/2.0.4 Perl/v5.10.0 Server at a-3230008389.phinger.dnsstuff.com Port 80

Indeed, a great tool, exactly what I expect from dnsstuff.com :-)
