Comcast is about to roll out gigabit-plus internet speeds for both upload and download without needing fiber upgrades that run all the way to the house. The company will offer a new “X-Class” service upgrade that supports up to 2 Gbps downloads and uploads starting in Colorado Springs, Colorado, next week.
