Well, I've tried it from a Windows 7 install here and still cannot get it up using Firefox or IE so it must be some sort of regional blocking. Windows troubleshooter under IE could not suggest an answer for this but there again that's hardly surprising.
$ nslookup tf.nist.gov Server: 127.0.0.1 Address: 127.0.0.1#53 Non-authoritative answer: tf.nist.gov canonical name = tf.boulder.nist.gov. tf.boulder.nist.gov canonical name = symp17.boulder.nist.gov. Name: symp17.boulder.nist.gov Address: 132.163.4.169 Seems to resolve fine but trying to ping it fails (still that is no indication of a problem). # nmap -PN tf.nist.gov Starting Nmap 5.00 ( http://nmap.org ) at 2010-05-28 02:37 NZST Interesting ports on symp17.boulder.nist.gov (132.163.4.169): Not shown: 999 filtered ports PORT STATE SERVICE 80/tcp open http Nmap done: 1 IP address (1 host up) scanned in 11.22 seconds Now this is interesting as I can see port 80 open so there must be something blocking this in the server. And yes, by all means flame me for nmap'ing a US government server if you like, I'm sure I'll be extradited for trying to hack into the system and sent to prison for 25 years, but if it's out there in the public space it should be secure enough for any form of 'attack'.
