RFC-255 is titled “Status of Network Hosts”. It's authored by Ellen Westheimer of BBN and dated October 26, 1971.
The technical content
The numbers this time:
- 47 dead
- 41 open
- 13 timed out
- 6 half open
- 1 refused
The percentage of open connections has gone up to 38% from about 25%, so that's an improvement. In the intervening 20 days since RFC-252, we see the following changes:
- Both of UCLA's hosts are completely online instead of intermittently offline
- Utah has gone from completely dead to sometimes-timed-out
- Harvard has gone from completely dead to sometimes-timed-out
- SRI NIC is online more often
