If you look at the Windstream forum at BroadbandReports, you'll see virtually everyone complaining about Windstream having ridiculous slowdowns during peak hours, and high latency almost always. As a subscriber, I can vouch for that, even though at my location the problem only started recently, long after everyone else was complaining. How the hell they think they can offer video over such a service is anyone's guess.
And I am truly shocked by the item that Tyralak posted. One of the things that I like about Windstream, vs. for example a cable company, is that since they're a phone company instead of an entertainment company, they don't seem to care what you do with their service. I'm surprised to see the possibility of this changing after all these years.
