It’s been just a week since US telecom regulators announced a formal inquiry into broadband data caps, and the docket is filling up with comments from users who say they shouldn’t have to pay overage charges for using their Internet service. The docket has about 190 comments so far, nearly all from individual broadband customers.

Federal Communications Commission dockets are usually populated with filings from telecom companies, advocacy groups, and other organizations, but some attract comments from individual users of telecom services. The data cap docket probably won’t break any records given that the FCC has fielded many millions of comments on net neutrality, but it currently tops the agency’s list of most active proceedings based on the number of filings in the past 30 days.

The FCC will surely hear from many groups with different views on data caps, but Chairwoman Jessica Rosenworcel seems particularly keen on factoring consumer sentiment into the data-cap proceeding. When it announced the inquiry last week, Rosenworcel’s office published 600 consumer complaints about data caps that Internet users recently filed.

“During the last year, nearly 3,000 people have gotten so aggravated by data caps on their Internet service that they have reached out to the Federal Communications Commission to register their frustration,” Rosenworcel said last week. “We are listening. Today, we start an inquiry into the state of data caps. We want to shine a light on what they mean for Internet service for consumers across the country.”
