I should probably have mentioned that in this sense I view “urban” as exclusive to “single family homes” - meaning I’m 
talking about high density modern urban with under grounding requirements - and high rise residential towers.

We are the opposite, we are presently enterprise, midsize, and exotic-small business only, and have no residential arm 
or support structure (or SLA expectations, or standards or lack thereof) of a residential connection.
