Perhaps Mr. Bellovin can refresh my memory ... the paper I'm recalling had specifications for 5 or so different levels of reliability and redundancy in data centers (able to withstand criminal attack, armed attack, conventional explosives, nuclear explosion, acts of God, etc.) and was interesting reading. The focus, as I recall, was on the level of engineering required to reach various levels of uptime (99.9, 99.99, 99.999, etc.). This ringing a bell for anyone else?Do you mean <http://www.donelan.com/design/general.html>?
doh! Indeed I do mean that file. I got Bellovin and Doneland mentally transposed for some reason. Apologies all (still thought that document was a good read, though). -- Scott Francis || darkuncle (at) darkuncle (dot) net illum oportet crescere me autem minui
