Internet T1 Cutoff

FYI, it seems that the connectivity to the host is
dropping back to its previous multiple 56K links rather than
the T1. Note this will not affect connectivity to the InterNIC
hosts or networks.

> Dear Major Paciorowski,
> The original scope of the Network Information Center (NIC) tasking

> As of 1 April 1993, the NSF split the Internet portion of NIC

> support services are now provided by the DOD NIC at GSI, and
> Internet services are provided by the InterNIC at Network
> Solutions' facility in Herndon, VA.  Therefore, support of Internet
> activities was deleted from the contract by DISA at the request of
> the NSF.
> As the last step in the process of splitting the NIC, the NSF has
> terminated the funding for the T1 circuit between FIX-EAST and the
> DOD-NIC effective 1 June 1993.  Therefore, GSI has issued a
> disconnect order for this service, effective 1 June 1993. 
> Internet traffic using this circuit will no longer be able to

> adverse impact, some MILNET customers may experience slowness or
> loss of connectivity to the NIC.  Those MILNET customers who are

> Please forward this information to other individuals and
