Phase 5 Step 6 Schedule

Tue Dec 14 20:11:17 UTC 1993

In the final step of the Phase 5 deployment, we will be upgrading both
the Washington DC CNSS and connected sites and the Hartford CNSS and
its connected sites.

Since a number of providers (PSI, Alternet, and NEARnet) have dual
attachment connectivity via these two CNSSs, we have staggered the
upgrades to minimize loss of NSFNET Backbone Service connectivity.

The following is our detailed schedule for Phase 5 Step 6:

   11:00pm 12/17 CE on site at Hartford/Washington POPs
   12:00am 12/18 C51, C59 Upgrade
