I got exactly the same response. It really sucks that the account went so downhill. It was awesome in the first 3 months. But now with even a little bit of use, it is throttled to death. I was able to stream netflix at their lowest 720p on my 2mb line, in the late afternoon on 3 stars. Now I can't even to that after 12 on 3 stars or 5 stars. On 5 stars in the late afternoon I'm throttled to 50% line speed. I am currently on 3 stars, after a while of it going excellent. After 12 I don't get full line speed either anymore. I sometimes peak 180KB/s but usually it goes at about 150KB/s with a lot of fluctations. Where it used to peak my line the whole time no matter what star rating I was on.
These accounts were awesome while they lasted. I hope someone from connection reads this and look into this. Because now they seem to just be overselling this special.
I see people are also complaining on the PLUGG thread, so it must be something up with IS. They must be overcapacity.

Reminds me of Afrihost.
