Note 21

Late in the third quarter we began to provide a biweekly report on Host status to the network community.  Status information is obtained from a daily "login" survey made from the prototype TIP at BBN.  This status reporting is provided partially in response to requests from the Network Working Group, and partially as a spur to the Host organizations to improve their network availability.  (During the single two-week period in the third quarter for which data was obtained, only five Hosts responded to "login" attempts more than 50% of the time; further, the usual response of one of these Hosts was to refuse the login.)
