Three Hosts which were not officially able to act as Server's at the time of RFC #240 are now able to do so. These Hosts are:

Request for Comments: 252                       Bolt, Beranek and Newman

Category: F, G.3                                          8 October 1971

NIC: 7696

   The purpose of this RFC is to report on the recent status of most

   Network Hosts.  During September 27 through September 29 the BBN

   prototype Terminal IMP (Network Address 158) was inaccessible due to

   hardware debugging.  The Network was, therefore, not examined on

   these days.

   Three Hosts which were not officially able to act as Server's at the

   time of RFC #240 are now able to do so.  These Hosts are:

         2                SRI (NIC)         PDF-10

         6                MIT (Multics)     H-645

         9                HARVARD           PDP-10

   The Harvard PDP-10, however, has limited core space.  They will,

   therefore, run the Telnet program only occasionally.

   The following two tables summarize the information on the Host status

   for September 30 - October 8.
