Need to read this in more detail
I've printed your document out (5 pp.) so I can read it fully & carefully.
I live in a 750-unit (5, 2-sided, 4-storey buildings) apartment complex (in Palo Alto, CA) & when I felt I wanted DSL service, I got negative experience reports from neighbors seeking service from the Telco itself. Then I learned that Darwinmail.net specialized in multi-unit housing & had a demo setup nearby. Also met one satisfied customer neighbor. So I gave Darwinmail a try. Installer came same week & no problems for the 2+ months since.
DSLReports speed testing (via 3 locations) at various times says I'm getting around 700 Kb/s symmetrical.
But I've never seen any mention whatever of Darwinmail anywhere on the DSLReports Web site!
I've heard they got a boost from Cisco when they were struggling financially. I think I've located the "head end" of their "T-1" Line (from here to Kentucky, they say!) as a large black box in the garage of my own building (near the complex's center).
