I was lucky enough to have access to a home hookup on a lower USI tier for a while. It was of course far and away the best Internets around locally (altho now it's prompted CenturyLink to roll out). Coverage maps here http://fiber.usinternet.com/
Another thing I loved was Comcast was forced to slash its rates in the covered zip codes dramatically, finally resembling a reasonable price. The solid upstream is very good for getting videos online, altho its true that the chokepoint winds up being the Youtube server, not the pipe. The entire time, except when someone doing laundry unplugged the basement router, it never really bogged down & you could tell the peering points were not saturated like is always the Comcast experience.
I happened to run into a bunch of the USI staff at an event & they explained to me that while they didn't have much capital, the little bit they were riding on could suffice to slowly build out the network. It took awhile to develop a process w the city to get easements on the boulevards but now proceeds smoothly. Conveniently everything is reliable (who knew buried optical cables are more reliable than coax on poles?) and the whole city network gets like 4-5 service calls a day. They were actually happy to not have to bother providing TV service w its finicky boxes, because they don't cover the whole city.
The ping times to the U of Minn timeserver at 18.104.22.168 were around 2-4ms if you don't go thru a router.
Obviously they were a bit proud they'd been able to hang in the biz over those years, and considered themselves the "last man standing" against the big monopolies.
