Cablevision took a massive public relations beating four months ago after an FCC study showed that the company failed to provide the speeds they advertised 50% of the time. Since then we'd noted that Cablevision had been quietly bumping delivered speeds, and yesterday the FCC confirmed that Cablevision had made serious strides over the last four months -- now delivering advertised speeds 90% of the time during peak hours. It didn't take long for Cablevision to seize on the announcement, and the company has filed a new lawsuit against Verizon for false advertising.

In a statement to the press, Cablevision says that despite the FCC's announcement only popping up yesterday, both Cablevision and Verizon had been aware of Cablevision's improvements for some time -- and after private conversation Verizon has refused to stop running ads that use the older FCC data. From the statement:Verizon sent Broadband Reports their own statement saying they plan to "vigorously" fight the lawsuit:As is usually the case, by the time this dispute is settled Verizon will have moved on to a new suite of ads anyway. We're interested in why the FCC only released data on Cablevision. Other carriers, like Frontier Communications scored poorly (delivering 67% of advertised speeds during peak hours) but the FCC didn't feel it necessary to deliver updates on their progress. We'll assume the FCC wanted to show how they were able to institute change simply by using data, though it would be nice to see if ISP's like Frontier (in the less competitive markets FCC policy hasn't done much about) cared quite as much about their poor showing.
