They still are not enforcing it. PTD cap is only for primetime useage. It was just raised to 250 but there useage is only measured like 5 to 11 pm. The letter is just letting them know. You would be hard pressed to find anyone that has ever gotten charged a overage. Basically they just want customers doing heavy downloads during off peak hours. You would have to be a really super super heavy user and then they just kick you off. It was really low before something in the area of 100 GB it was raised 3 and half times or so. Bottom line is its actually more now and thats what the letter is about. being it only covers the evening nothing has really changed.
