Comcast subscribers do not have much to brag about in the way of customer service—the ISP was voted Worst Company in America by Consumerist readers in 2010 and 2014—but when it comes to download speeds, its Xfinity service is tops in the US. That is according to Ookla's Speedtest data.

The 2017 US Market Report by Ookla is based on Speedtest intelligence data captured during the first half of 2017. During that time, over 26 million unique users performed more than 111 million tests with Ookla's online Speedtest tool.
