Try looking under Sean Donnelan (sp? Sorry Sean).
I think you are referring to something he did. However, I don't remember for sure.

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 centers ... [searches] argh. I can't find it yet. 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.).
Not me.
