RFC 366
Network Host Status
Network Host Status ✨
RFC # 366 🎀 (NIC # 11013)
- Title: Network Host Status
- Author: Ellen Westheimer, BBN
- Date: 11 July 1972
- Category: F. G.3
- Updates: RFC #362
- Obsoletes: None
The Tea ☕
okay so this RFC is literally a status check on most of the Network Hosts from June 19 to June 30. 💅 that's the whole vibe.
No testing happened on June 20 because they were trying to install the new IMP system. the chaos was real 😭
Several Hosts are currently left out of the daily testing because they're basically just users right now. 🫶 That includes the Terminal IMPs that are in the Network at the moment: AMES, MITRE, RADC, NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, and BBN*. This group also has the Network Control Center computer (Network address 5), which is only used to gather statistics from the Network. 📊
The hosts below are also in this "users only" squad ✨

- D = Dead 💀 The Destination Host is either dead or can't be reached from the BBN Terminal IMP. That can be because of network partitioning or a local IMP failure.
- F = Full 🙈 The Destination Host opened a connection, told the user that all Network ports were in use, and immediately closed the connection.
- H = 1/2 Open 🥲 The Destination Host opened a connection, but then it either closed it right away or stopped responding.
- O = Open ✨ The Destination Host opened a connection and was accessible to users. slay.
- R = Refused 🚫 The Destination Host returned a CLS to the initial RFC.
- T = Timed out ⏰ The Destination Host didn't finish the ICP and open a connection within 60 seconds.
Footnotes Are Lowkey Important 🧚
* BBN Terminal IMP The BBN Terminal IMP (Network Address 158) is a prototype. so it's frequently not connected to the Network, because it's being used to refine and debug the Terminal IMP programs. 🛠️
* UCLA NETRJS 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, so we're assuming that a successful initial connection to the NETRJS logger means NETRJS is also working. 🤞
# Sites that might be offline These sites advertise that they may not have their system available at these times. 😬
