RFC 362
Network Host Status
Heyyy bestie 💖 okay so this RFC is basically a group chat status check for the whole Network 🌐✨
NETWORK HOST STATUS ✨
So the paperwork first 🎀 This one's by Ellen Westheimer at BBN (NIC #10604), it's RFC #362, dated 28 June 1972, and it's filed under categories F and G.3. It updates RFC #353 and obsoletes None 💅
Okay so from June 5 to June 16, we're checking in on most of the Network Hosts 👀 During that stretch the MIT Math Lab PDP-10 (Network address 198) became a server 🖥️🔥
No testing on June 6 because they tried installing the new IMP system 🛠️ And no testing on June 9 because the prototype Terminal IMP was busy being used for software debugging 💀
On June 16, the ARPA Terminal IMP (Network 156) got installed in Arlington, Virginia 📍🌸
Several Hosts are currently excluded from the daily testing 🙈 They fall into two groups:
- Hosts that aren't expected to be working on the Network as servers (available for use from other sites) on a regular basis for at least two weeks. The only Host in this group is the PDP-10 at Case (Network address 13).
- Hosts that are currently meant to be users only 💜 This group includes the Terminal IMPs that are presently on the Network (AMES, MITRE, NBS, ETAC, USC, GWC, NOAA, RADC, SAAC, BELVOIR, ARPA, and BBN*). It also includes the Network Control Center computer (Network address 5), which is used solely for gathering statistics from the Network. And finally, these Hosts are in this group too:

12 Illinois PDP-11
19 NBS PDP-11

*The BBN Terminal IMP (Network Address 158) is a prototype, so it's frequently not connected to the Network. It's being used to refine and debug the Terminal IMP programs.

D= Dead (Destination Host either dead or inaccessible [due to network partitioning or local IMP failure] from the BBN Terminal IMP.)F= Full (Destination Host opened a connection, informed user that all Network ports were in use, and immediately closed the connection.)H= 1/2 Open (Destination Host opened a connection but then either immediately closed it, or did not respond any further.)O= Open (Destination Host opened a connection and was accessible to users.)R= Refused (Destination Host returned a CLS to the initial RFC.)T= Timed out (Destination Host did not complete the ICP and open a connection within 60 seconds.)
*The only service currently offered by the UCLA IBM-360/91 is a Network Job Service (NETRJS). The BBN Terminal IMP isn't equipped to test NETRJS, though. We're assuming that an initial connection to the NETRJS logger means NETRJS is also functioning. #These sites advertise that they may not have their system available at these times.
