I am a firm believer that Bell Aliant has adopted the "you can do what you want as long as you don't interfere with others" and with FibreOP the amount of bandwidth they have to play with truly is astonishing.
To that extent one month I've used over 3TB of bandwidth, another over 2TB. For the month of March I used just 1.7TB. (I say just but really that is a lot)
I have yet to get any sort of email, phone call, etc from Bell Aliant.
