Re: Business class / Extreme Tier? If your on the extreme tier you still on the residential side, so probably the 250GB cap will be in place on it. I hope that comcast will upgrade the caps on their extreme tier to something more reasonable for those speeds, like 400GB/month, but I'm not holding my breath.
I'm glad that I have their business class internet if there won't be any caps enforced now. I do about 300-350GB/month on my 16/2 (which is the fastest I can get).
