Our Network

We’re building a next-generation connectivity experience with a simple purpose: connect our customers—now and in the future—to more of what they love.

Our network is the result of years of investment and innovation that continues to get smarter, faster and more reliable. It delivers a next-generation broadband experience to millions of homes and businesses to support the increasing demands of our customers today, and in the future.


Homes and businesses with speeds faster than a gig.


Our customers connect nearly a billion devices a year.


Network diagnostic speed tests performed most days.

For years, we’ve made strategic investments in building capacity to meet our customers’ current needs and stay well ahead of future demand. Connectivity is the center of our customers’ lives, so we’ve built a network that combines gig speeds with wall-to-wall WiFi coverage in the home, and more than 23 million outdoor hotspots to provide the speed, coverage and control they need, wherever they go. Since 2018, we’ve funded the largest network upgrade in the United states, including:


Investing more than $20 billion to evolve and grow our network over the last 5 years


Built 50k new route miles of fiber into our network
