Cox decides 300 megabits is enough for now. Mari Sibley asked the right questions and got a major story. Until recently, it appeared almost all the cable companies would offer gigabit DOCSIS 3.1 to most subscribers, making a gig available to almost 90% of the U.S. very quickly. Almost half were due to be covered by the end of this year. Many more would come in 2018, when Comcast promised to cover all of their ~40% of the U.S. Cox, #3 in the U.S. with 6M customers, had initially promised to offer a gig to all of them by the end of last year. They've backed off, VP Philip Nutsugah tells Sibley, without revealing the motivation. Comcast, as far as I know, is still going rapidly on gigification with availability to about 40% of the U.S. still scheduled for the end of next year.
