They are consistently throttling back if you are in the top 5% (over 2 Gb a month) I went over that amount for the last 2 months. Prior to that my speeds were always close to 1.5 Mbs, now since the throttling has begun, alway near 0.5 Mbs, no matter where I go. The fact that they say they only throttle back if congested is a scam. To them, one other user on that tower means it's congested and they throttle you back. oddly, my upload speed are now higher than my downloads speeds. And you can always tell when you are being throttled. Run the speed test, and watch it spike up over 1.5 Mbs for a short time, and then drop way down.
