Pretty Spot on Actually BlueArcher..
I don't know where they stand, but from some of the fiber trenching guys I've talked to and some Windstream Field Techs I gather Windstream (and I suppose other Major Carriers) are putting more focus on Fiber to the Cell Towers ahead of upgrades to their own networks (IE fiber to remote dslams, actual carts in the DSLAMS moving from adsl(2,2+,etc) or Central Office Equipment.
To the OP. Odds are they replaced the fiber to the DSLAM. If they didn't replace anything else in said DSLAM odds are your still in the same boat; 8500 ft from the CO maybe 3mb at best speeds. Maybe consistent 3mb speeds though
