OFFICIAL Topic: - MILNET/ARPANET SPLIT - TEST DAYS ---------------------------------------------------------------------- As described in newsletters 26 through 29, the ARPANET will be split into the MILNET and the experimental ARPANET on October 4, 1983. In preparation for this split, two full scale test days have been scheduled in September. THESE TEST DAYS ARE THURSDAY, SEPTEMBER 8 AND THURSDAY, SEPTEMBER 15. The tests will involve complete cutover to the split configuration of the two networks. The tests commence at 12:00 NOON EST and terminate at 12:00 NOON EST the following day. Host administrators must ensure that new host name tables are loaded at the start and finish of the tests. (An upcoming Management Bulletin will have further details on host table updating.) For hosts moving to MILNET, administrators must also ensure that their host uses its new network 26 address during the test period. During the tests, users of TACs should be aware of the network alignment of the TACs and hosts they use. Every effort should be made to use a TAC on the same network as the host being accessed. Further details concerning the split, and its ramifications for users and administrators, may be found in the above-mentioned network newsletters. --------END-OF-MESSAGE------ -------
