Network Working Group Alex A. McKenzie Request for Comments: 638 BBN-NET NIC: 30538 April 25, 1974

              IMP/TIP Preventive Maintenance Schedule
    This RFC corrects numerous inaccuracies in RFC #633.  Rather than
    trying to list all the changes, I urge all Liaisons and other
    interested parties to look carefully at the times now listed for
    the sites they are interested in.
 This note presents the current IMP/TIP Preventive Maintenance
 schedule.  Preventive Maintenance is scheduled on a monthly basis and
 a given machine is normally scheduled at the same time each month;
 wherever possible the time is chosen to coincide with the PM time for
 the Host(s) at the site.
 It is sometimes necessary to reschedule PM's because of network
 connectivity considerations or for other reasons.  Whenever this is
 necessary we will follow the usual procedure for scheduling down time
 with our "primary contact" at the site.  Permanent changes to the
 schedule will he announced via the RFC mechanism.
 PM's normally do not require the IMP/TIP to be taken down.  However,
 machines must be taken down in some cases, so no one should rely on
 the machine remaining available through the PM period.
 PLEASE REMEMBER THAT TUESDAY MORNINGS FROM 7am TO 9am ARE RESERVED
 FOR NETWORK SOFTWARE MAINTENANCE.
