Who needs Google Fiber? By itself, the Chattanooga Electric Power Board was able make Tennessee the home of the first city in the United States to offer city-wide gigabit Internet service, but it’s not stopping there. Yesterday, the city-owned utility announced that all of its 170,000 customers can now purchase ten gigabit Internet service, making it the third city to do so. What’s funny is that after Comcast tried, and failed, to sue the utility, it decided to launch its own two gigabit Internet service in Chattanooga, but now there’s a ten gigabit service that costs the same amount.
