RE: DNS .US outage

["Church, Chuck" <cchurch () netcogov com>]

 Thanks for your help, guys.  Didn't know dig existed for windows.
Several ISPs (charter.net, alter.net) are choking on .us queries right
now, but AT&T's name server is working ok for me.  Here's one failing on
.us, but .com works fine:

C:\temp\dnstools>dig @24.197.96.16 com NS

        Is it possible that one of the authoritative servers for .us is
unreachable/down at the moment, at least from name server 24.197.96.16's
point of view?   198.6.1.2 gives similar results.

Thanks again,

The web directory:
http://www.isc.org/index.pl?/sw/bind/bind9.php

or the ftp directory:
ftp://ftp.isc.org/isc/bind/contrib/ntbind-9.3.1/BIND9.3.1.zip

What is also very useful are the following two websites, so people can
click around a bit and get nice pictures making everything crystalclear
for them:

DNSDoctor (which even supports IPv6 :)
http://demo.dnsdoctor.org/

And of course DNS report:
http://www.dnsreport.com/

Greets,
