Network Working Group D. Walden RFC # 548 BBN-NET NIC # 17794 August 16, 1973
Hosts Using the IMP Going Down Message
As given in BBN Report 1822 (Specifications for the Interconnection
of a Host and an IMP), IMP to Host message type 2 specifies that the IMP local to the Host is going down; the message further says when the IMP is going down, for how long, and why.
When the IMP goes down after sending the IMP Going Down message to
the Host, the Host's network users and local users of the network will not, in general, be forewarned unless the Host sends a message to these users. We therefore urge all Hosts to warn their network users and users of the network of impending IMP downs; just logging the received IMP Going Down message on a logging teletype, as many Hosts currently do, seems insufficient.
Incidentally, please remember that Tuesday mornings from 7 a.m. to 9
a.m. (Eastern Time) are reserved for Network Software Maintenance, as announced in RFC #440.
