Internet speeds are getting faster in the United States, especially in cities such as Kansas City, Austin, Seattle, San Francisco, and Phoenix, according to a new Speedtest Market Report. The report, by Ookla's popular service, found that fixed broadband customers saw the biggest jump in performance this year with download speeds achieving an average of over 50Mbps for the first time ever. The result marks a 40 percent increase since July 2015. From a TechCrunch report: That average, 54.97 megabits per second is 42 percent higher than the same period last year, and upload jumped even more -- 18.88 is 51 percent higher year over year. This is all based on the 8 million or so daily tests conducted on Speedtest's website and apps, by the way, so the data is pretty sound. Comcast Xfinity took the honors for fastest speed on average, but its 125 megabits wasn't that much higher than the competition: Cox with 118 and Spectrum with 114. [...] On mobile, Verizon and T-Mobile are tied for first place with 21 megabits and change download speed on average, though the latter beats the competition by a long shot with upload speeds averaging 11.59 megabits. Poor Sprint, though.
