RFC 548

Hosts Using the IMP Going Down Message ✨

Okay bestie, this is RFC 548 🎀 It's from the Network Working Group, written by D. Walden of BBN-NET (NIC # 17794), and it's dated August 16, 1973. The header doesn't say what it obsoletes or updates, and it doesn't list a category either. 🌸

So in BBN Report 1822 (Specifications for the Interconnection of a Host and an IMP) 💜, there's this IMP to Host message type 2 that tells the Host its local IMP is going down. It also says when the IMP is going down, how long it's down, and why 🙈 Iconic info, honestly.

Here's the tea 🫖 When the IMP goes down after sending the IMP Going Down message to the Host, the Host's network users and local users of the network usually won't get a heads-up unless the Host sends them a message. So we're literally begging all Hosts to warn their network users and users of the network about impending IMP downs 😭 Just logging the IMP Going Down message on a logging teletype, which lots of Hosts do right now, is giving not enough 💀

Also, reminder 🧚 Tuesday mornings from 7 a.m. to 9 a.m. (Eastern Time) are reserved for Network Software Maintenance, as announced in RFC #440. Put it in your planner, babe 📅✨
