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.
