In a bit of good news for Comcast subscribers — a rare bit of good news, some might argue — a new report suggests that the company is about to double or even triple its Internet data speeds for some subscribers. DSLReports on Tuesday afternoon cited an anonymous source in claiming that Comcast is preparing to increase data speeds for some subscribers. Speeds were already boosted for many users less than a year ago, but the ISP apparently isn’t done widening pipes for its customers. According to the report, Comcast plans to increase download speeds on its “Performance” tier from 25 Mbps to 50 Mbps. Subscribers on the “Blast” tier will see speeds jump from 50 Mbps to 105 Mbps, and the “Extreme” tier will nearly triple from 105 Mbps to 305 Mbps. Why is Comcast increasing speeds so soon after the last bump? DSLReports isn’t shy in sharing a theory.
