Let me also add, as further evidence of throttling, that I checked my connection on one instance by going to YouTube. I watched a high def video with no problems. I also went over to CBS and watched some streaming video with no problems. Vimeo, no problems. Then I went back to Netflix and tried again, and got the same old "your connection has slowed..."
I moved here to Tempe Arizona from Haiku, Maui, Hawaii two weeks ago. In Hawaii I could watch Netflix streaming video on my DSL connection with no problems at all. AND, my connection there was most def slower than here, and the telcom infrastructure there is behind what it is on the mainland USA. Explain that as BS please!
