AT&T’s global network carries an average of one exabyte of data per day, an increase of more than 1,000% over the past decade.
For decades, AT&T has been at the forefront of connecting people and businesses, continually pushing the boundaries of what’s possible. This relentless drive has resulted in a reliable network that now moves an exabyte of data – one billion gigabytes - across our network on an average day.
Let’s Put That Into Perspective
An exabyte is an almost unimaginable amount of data. It's the equivalent of streaming billions of hours of video or trillions of songs. It’s like stacking 20 billion filing cabinets on top of each other or downloading every book ever written, thousands of times over, every single day. If you streamed HD video 24/7, it would take you over 32,000 years to watch 1 exabyte of movies! Every photo, video, message, and email our customers send and receive adds to this incredible total, demonstrating the vast scale our network supports daily. Handling this amount of data requires a network that is not only powerful, but also reliable and highly secure, so you can stay connected with confidence. This level of data is possible when you have the largest wireless and Fiber network in North America.1 But our leadership doesn’t stop at size; we also have the Best Overall Wireless Network Performance, Most Reliable Wireless Network AND Fastest Wireless Network2 of any carrier.
Extraordinary Growth
Just ten years ago, we moved only 91 petabytes of data across our network each day. The leap to an exabyte marks an astonishing 1,000% increase over the past decade and more than 11,000% increase over the past 20 years! With 2025 in the books, we saw extraordinary growth that redefined what’s possible for our network. Here’s a look at the numbers below:
Empowering a More Connected Future
Looking ahead, the future of AT&T will be shaped by our steadfast dedication to innovation, strategic investments in advanced infrastructure, and a relentless focus on keeping people connected wherever they are and whatever they do. As data demand continues to surge, AT&T is poised to meet the challenges of tomorrow by investing in cutting-edge technologies, expanding our fiber and 5G networks, and enhancing network reliability and speed. With a focus on building the networks of the future, we're dedicated to helping ensure that the next era of connectivity is faster, smarter, and more accessible for everyone.
