Verizon, the nation’s leading provider of fiber-to-the-home service, doesn’t offer a gig, or even half that speed. Instead, it markets a “fastest” service that is only 50 megabits a second for downloading and 20 megabits a second for uploading. It costs $144.99 a month. That’s one-twentieth the speed of Hong Kong Broadband’s service for downloading, for more than five times the price.
