Anyone with a backup? Even archive.org doesn't have it https://web.archive.org/web/*/http://cm.bell-labs.com/cm/cs/...

Server: Plan9
It's on plan9 so it will be in the dump. Plan9 does daily incremental backups.

It's not shown up on 9fans yet, I've passed it to someone who can help
The message will get to Geoff / Jim who should sort it out
