Actual broadband speeds may vary ... by quite a bit.
Looking through the FCC's rankings, Comcast came out top with a better-than-advertised speed of 144 per cent (thanks to its investment in bandwidth-crunching DOCSIS 3.0 technology), followed in a distant second place by Verizon's FiOS FTTH service with 116 per cent. However, the bad boys were Cablevision and Frontier - with Cablevision scoring just 50 per cent and Frontier doing not much better (surprise, surprise) with 67 per cent.
