RFC-240
by Darius Kazemi, August 28 2019
In 2019 I'm reading one RFC a day in chronological order starting from the very first one. More on this project here. There is a table of contents for all my RFC posts.
Corrected statistics
RFC-240 is titled “Site Status”. It's authored by Alex McKenzie of BBN and dated September 30, 1971.
The technical content
McKenzie is issuing a correction to RFC-235, which published statistics about the the various sites around the network. He apologizes profusely in the opening for “any embarassment this may have caused to anyone associated with the Network”.
The new aggregate stats are, by my count:
- 57 dead (+1 from prior)
- 34 open (+1 from prior)
- 16 timed out (-1 from prior)
- 9 half open (-1 from prior)
- 4 refused
Analysis
These stats are really not very different from the ones reported in RFC-235! Specifically the discrepancies are:
- BBN was fully open rather than half open for one test
- MIT(DM) is dead at one point rather than half open
I'm not sure why McKenzie's apologies are so profuse!
