AT&T now carries an average of one exabyte of data per day across its global network, underscoring the scale of traffic growth driven by mobile video, cloud services, and enterprise connectivity. One exabyte equals one billion gigabytes, marking a major benchmark for a single operator’s daily network load.
AT&T reported that daily traffic has increased by more than 1,000% over the past decade, up from roughly 91 petabytes per day ten years ago. Over a 20-year period, the company said daily traffic has expanded by more than 11,000%. The growth reflects rising consumption across wireless, fiber broadband, enterprise networking, and cloud-connected applications.
To support this scale, AT&T continues to expand fiber and 5G infrastructure while investing in core network modernization and automation. The company positioned these efforts as essential to maintaining reliability, security, and performance as data volumes continue to rise across consumer and business services.
• Average daily traffic now exceeds 1 exabyte (1 billion GB)
• Daily network load has grown more than 1,000% in the past decade
• Traffic increased more than 11,000% over the past 20 years
• Growth driven by mobile video, broadband, cloud, and enterprise demand
• Continued investment in fiber, 5G, and core network infrastructure
“Our network now moves an exabyte of data on an average day, reflecting how central connectivity has become to everyday life and business,” said Robert Walters, SVP of Network Planning, Construction & Engineering at AT&T.
🌐 Analysis
AT&T’s traffic milestone highlights how large-scale carrier networks are absorbing workloads once concentrated in data centers, driven by cloud services, video streaming, and AI-enabled applications at the edge. Similar traffic growth trends are pushing operators globally to accelerate fiber densification, 5G core upgrades, and software-defined networking to manage scale without proportional cost increases.
