IMP tests you
RFC-256 is titled “IMPSYS Change Notification”. It's authored by Bernie Cosell of BBN and dated November 3, 1971.
The technical content
This notification says that a new version of the IMP will be installed soon. There is an increase in the amount of time a host has to wait after connecting to an IMP before sending messages over the network, and the IMP can now remotely test a host connection under the direction of the Network Control Center at BBN.
