Most Comcast customers now have a 1TB home internet data cap

Comcast's home internet data caps are going live for a majority of customers starting November 1st.

Called the "Xfinity Terabyte Internet Data Usage Plan," the cap restricts the amount of data you consume in your home to 1TB per month regardless of the speed of your plan. Comcast claims 99 percent of customers use less than 1TB per month, but it does now offer an unlimited option for $50 more per month. Comcast says it will never throttle customers who go over the cap, but it will automatically add 50GB to your plan at a cost of $10. The company will continue to charge you $10 in 50GB intervals up to $200 a month. To notify customers, the company will use in-browser, email, and text notifications starting at the 50 percent point, and a usage meter is available on your online account. Comcast says customers will get two grace months every year, meaning you won't be charged unless you exceed the cap a third time in any given 12-month period.
