Independent rating service of colocation facilities

[Sean Donelan <sean () donelan com>]

Is there an independent rating service of colocation and hosting
facilities.  For example, when a hosting company claims they have
"Class A" space (whatever that means), does anyone actually check?

Or if there isn't, would people be interested in such a service
similar to what Underwriters Laboratories or Factory Mutual does
for alarm monitoring central offices; but for Internet colocation
and hosting facilities?
