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

; <<>> DiG 9.3.1 <<>> @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.

It is perfectly possible. Unfortunately, all three nameservers of
".us" are behind the same AS and, unfortunately, they are all in the
same /16. Checking the filters is a first step.

PS: tracert exists on MS-Windows and c.gtld.biz replies to it.

the alter.net cache's you are using arent' guaranteed to work...
especially for non-customers :slight_smile: but... in general they do work, sometimes
slowly as all manner of people use them regardless of their 'customer'
status to alternet :frowning:

I'm not seeing these problems though (though that problem might have been
transient too)
