"DSL is terrible, but it doesn’t have to be," writes Rob Pegoraro, who has written regularly for The Washington Post and USA Today. He's on target that the telcos offer about half the country an awful service, 10-15 year-old DSL at speeds of 2-10 megabits. That's terrible today and customers are flocking to cable. But he also reports that #1, AT&T and #3, Centurylink, are getting serious about G.fast at 500 megabits and more.
Rob picked up my comment, "G.fast will be a real factor in 2017 but for a relatively small number of homes," and went on to call G.fast "A new hope." My guess is that both AT&T and Century will start deploying widely in the second half of 2017.
