I don't know if it qualifies as an "established standard", but ISTR that
Steve Bellovin had a paper about various levels of reliability in data

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).
