Ex PSI legacy .us domains inactive

Over the weekend a customer of mine had his legacy .us domain
under .rye.ny.us stop working, as it is no longer in the root servers.

After doing some checking, a whois on rye.ny.us shows it as inactive.
The customer found this list of .us delegations:

http://www.neustar.us/delegated_managers/delegated_subdomains.txt

A random check shows every domain listed as being with psi.net as inactive.
I'm about to write a little script to check all the psi domains in that
list.

This is basicly a heads-up if anyone else has a domain that might be in the
same catagory, or if someone from Neustar is listening, the customer's
attempts to contact them so far haven't been fruitfull.

The PSI deleted domains are mostly NY cities.
