AT&T Hits Historic Milestone: 1 Exabyte of Data Daily

For decades, AT&T has led the way in connecting people and businesses, always pushing the limits of what is possible.

This continuous drive built a trustworthy network that now moves an exabyte of data—one billion gigabytes—on an average day.

Putting That Into Perspective

An exabyte is hard to wrap your head around. To help you picture the sheer scale our system supports, one exabyte equals:

• Billions of hours of streaming video.
• Trillions of songs.
• 20 billion filing cabinets stacked high.
• Downloading every book ever written, thousands of times over, every single day.

If you streamed HD video nonstop, it would take more than 32,000 years to watch one exabyte of content!

According to AT&T:

Handling this volume takes a network that is powerful, secure, and steady so you can stay connected with confidence. We support this level of traffic thanks to operating North America's largest wireless and fiber network.

Rapid Expansion

Ten years ago, we moved just 91 petabytes of data daily. Reaching an exabyte represents a 1,000% jump over the last decade and an 11,000% rise over the last twenty years. The growth seen in 2025 redefined our network's potential.

Powering a Connected Future

Moving forward, our future rests on a commitment to new ideas and smart infrastructure updates, keeping people connected wherever life takes them.

AT&T further reiterated by saying:

As the world asks for more data, we are prepared to answer that call. We are putting resources into advanced tech, growing our fiber and 5G reach, and boosting speed. We are building for the long haul to make the next era of connectivity faster, smarter, and available to everyone.
