Most internet users will probably not be affected by Comcast’s decision to roll out its data caps to more markets. But those people who consume a lot of media of the high-definition streaming variety and console games may find ways to surpass that 1TB monthly cap.

It sounds like a lot of monthly traffic, and for the average user, it probably is. But households with multiple internet users who do a lot of streaming of 4K video and PlayStation/Xbox game may feel the burn.

What happens if you go over that cap? For the first two times in a period of 12 months, there will be no overages. But the third time you go over your allowance, you’re going to be charged $10 for an additional 50GB of data to a maximum of 200GB of extra data. You will be able to monitor your data consumption and set alerts to tell you when you reach a certain threshold.

Comcast says that you can do a log with a terabyte of data each month — that’s what its press release is about. The company says that more than 99% of its subscribers do not use 1TB of data in any given month and that its data plans are based on a “principle of fairness.” There are many Comcast users who will probably not agree with the company’s definition of fairness.

That said, if you’re a Xfinity subscriber in the following markets, you’re already on a capped data plan: Alabama (excluding the Dothan market); Arizona; Arkansas; Florida (Fort Lauderdale, the Keys, and Miami); Georgia (excluding Southeastern Georgia); Illinois; Northern Indiana; Kentucky; Louisiana; Maine; Southwestern Michigan; Mississippi; Tennessee; Eastern Texas; South Carolina; and Southwest Virginia.

On November 1st, the 1TB data cap is hitting the following markets: Alabama (Dothan); California; Colorado; Florida (North Florida, Southwest Florida and West Palm); Southeastern Georgia; Idaho; Indiana (Indianapolis and Central Indiana; Fort Wayne and Eastern Indiana); Kansas; Michigan (Grand Rapids/Lansing, Detroit, and Eastern Michigan); Minnesota; Missouri; New Mexico; Western Ohio; Oregon; Texas (Houston); Utah; Washington; and Wisconsin.
