Want to know if your ISP is capping data? Check our updated chart


As we prep for the launch of two new consoles that will allow people to download games that are 30 GB to 50 GB in size, and as new research comes out showing that over-the-top television viewing is rising, it’s worth taking an updated look at how ISPs around the U.S. are trying to implement caps.

We wrote our original chart in October 2012, noting that at that time 64 percent of Americans were covered by a cap at the end of 2011. Today (or rather, at the end of the second quarter) the percent of American broadband subscribers covered by a cap remains the same. However, the caps themselves are changing.

Comcast still hasn’t settled on a particular capping scheme yet, although it is expanding its 300GB capped plan that offers overage charges of $10 for every 50 GB over the limit. Meanwhile, Cable One has changed what was a complex cap scheme that was based on time of day and service tier into a blanket cap determined by the speed of broadband you buy.

AT&T has decided to implement a cap on its gigabit service, although it hasn’t determined what that cap might be. Meanwhile, CenturyLink has decided not to cap its gigabit customers. Time Warner Cable is expanding an opt-in program that offers discounts to users if they accept a cap — a program that Comcast is trialing as well. The Time Warner program is now offering a $5 discount and an $8 discount on its 2Mbps, 3Mbps and 15 Mbps tiers so users who stay below a 5 GB cap get $8 off the retail price, while users staying below 30 GB get $5 off the retail price. These are opt-in plans.

In most cases, the companies implementing caps maintain that 99 or 98 percent of their users don’t go over them and have median usages that range between 12 and 18 GB per month. So here are the top broadband providers in the U.S. and their caps. Last year we included a column for exceptions to the cap, but this year there aren’t any, so we took that column out.
