Sorry,
"Gartner said every location that requires mission-critical internet connectivity, including externally hosted websites, should be multi-homed"
is common sense. If you have something 'mission critical' to your business you had better have more than one link out... It'd make great sense to make sure that the links in question atleast didn't end up on the same router at the far end, and while you are at it, get them to different providers (hopefully) in different telco-hotels.
Tier-2s should be given much more credit than they typically are in write-ups like this. When a customer is single homed to a tier-2 that has multiple tier-1 upstreams, and uses a delegated netblock from the tier-2's aggregations, that means one less ASN and one or more less routes in the global table.
I'm not such a believer in the tier-n classifications, single homing a critical resource is just dumb, regardless of the 'tier' you stick it in. gartner, as gartner normally does, is just stating the obvious and making money doing it.
