RFC 330
Network Host Status
Network Host Status ✨
okay bestie, this is RFC 330, titled NETWORK HOST STATUS 🦋. It was written by Ellen Westheimer of BBN (NIC #9923) for the Network Working Group, dated 13 April 1972. Its categories are F and G.3, it updates RFC #326, and it obsoletes nothing. 💅
The Big Picture
This RFC is a status report on most Network Hosts from March 27 to April 7 🌸. The PDP-10 at Ames, which acts as a front-end to the Illiac (Network address 15), became a server during this stretch 🔥. But ngl, this Host won't be open to general use for several months 🙈. Also, a Terminal IMP got installed at the University of Southern California (Network Address 23) on March 29 🎀.
Several Hosts are currently excluded from the daily testing 💀. They fall into two categories:
- Hosts that aren't expected to work as servers (available for use from other sites) on a regular basis for at least two weeks. Included here are:
Network
Address Site Computer
------- ---- --------
134 MIT-AI PDP-10
13 Case PDP-10- Hosts that are currently meant to be users only. Included here are the Terminal IMPs, which are presently on the Network (AMES, MITRE, NBS, ETAC, USC, and BBN*) 🧚. This category also includes the Network Control Center computer (Network Address 5), which is used solely for gathering statistics from the Network 📊. Finally, these Hosts are included too:
Network
Address Site Computer
------- ---- --------
7 Rand IBM-360/65
73 Harvard PDP-1
12 Illinois PDP-11
19 NBS PDP-11The tables on the next two pages summarise the Host status for this period 💜.
*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 🛠️.
The Snapshot: Who Was Open When
Here's the daily status grid, with times in Eastern 🕐. The footnotes after it are important, so don't skip them 👑.

D = Dead (Destination Host either dead or inaccessible [due to network partitioning or local IMP failure] from the BBN Terminal IMP.) 💀
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 the UCLA IBM-360/91 currently offers 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 working too 🤞.
