The Uptime Institute has a tier classification based on redundancy levels.
Various levels and types of system redundancies can result in any where

I have toured many sites and getting a Tier IV classification is quite
difficult. The goal is also to associate designs with potential
availability levels, but that is very system specific.
If the objective is to use the term "Class A", I think there is some
liberty in the interpretation. If the goal is to achieve an availability
objective, I would recommend having an objective 3rd party run a
reliability simulation.
Not being fececious, but can you point me at these? I always though a CO/DC
built TO NEBS and Bellcore was "Class A" "Tier 1" "Tier IV" etc.
