                    Scheduling IMP/TIP Down Time

From time to time it is necessary for an IMP or TIP to be taken down other than during its scheduled Preventive Maintenance period. Examples of such cases are retrofit programs and the off-line diagnosis and repair of intermittent problems. In the past we have scheduled these downs with our "primary site contact" at the affected site; in our view this individual was responsible for representing all of the hosts (and TIP users) connected to that IMP/TIP. Although this policy has worked well in the past, the recent proliferation of Very Distant Hosts, together with complaints from representatives of other (local or distant) Hosts, has caused us to review our procedures.

This note announces a modification of the previous policy. We will continue to schedule IMP/TIP downs with our "primary site contact." We will continue to consider this individual a representative of all Hosts connected to that IMP/TIP, with the following exception. Any Host organization wishing to be notified by telephone that down time has been scheduled for their IMP/TIP may nominate some individual as a "secondary contact." The name of the secondary contact, together with a telephone number where he/she can be reached, should be submitted to me by any of the following methods:

  US mail
      Network Control Center
      Bolt, Beranek and Newman Inc.
      50 Moulton Street
      Cambridge, Mass. 02138
      ATTN: Alexander McKenzie
  Journal system
      Ident = AAM
  Network mail

The NCC operators will notify the secondary contact by telephone after scheduling down time with the primary contact.
