US network operator Lumen says AI bots top web traffic

Lumen Technologies, a US enterprise networking company, said CEO Kate Johnson believed more than half of internet traffic is now generated by AI bots, urging businesses to rethink network capacity and cyber defenses as data flows become less predictable.

In an open letter, Johnson said companies that buy fixed network capacity may need more flexible usage-based models as AI systems raise traffic volume and speed.

Since taking over in November 2022, Johnson has sold Lumen’s consumer fiber business to AT&T for US$5.75 billion, used US$4.8 billion to cut debt, and Lumen said it used AI tools to spot activity tied to the Salt Typhoon hacking group in late 2024.

🧠 Food for thought

Implications, context, and why it matters.

Independent web data suggests AI bots are still a relatively small share of page requests

  • Lumen Technologies’ CEO says AI bots drive more than half of internet traffic, while a 2025 slice of web data paints a narrower picture.
  • In a dataset limited to HTML page requests, AI bots made up 4.2% of requests, while Googlebot, Google’s web-crawling bot, made up 4.5% 1.
  • Bot activity can top 50% for certain measurements. In Cloudflare’s early 2025 HTML analysis, non-AI bots handled about half of requests, yet AI bots remained a small fraction within the same dataset 1.
  • Even with fewer requests, AI crawlers can put outsized pressure on networks.
  • AI training crawlers from companies such as Anthropic, an AI model developer, pull large volumes of data, with crawling-to-referral ratios as high as 500,000-to-1. That gap helps explain why businesses may seek more flexible network capacity models even when AI bots stay a minority in this dataset 1.

Legacy telecom companies are using AI to reshape their own operations

  • At Lumen, the AI effort covers new products plus work to steady finances and day-to-day execution.
  • Lumen relies on AI software from Palantir, a US data analytics company, tied to an internal target of US$1 billion in cost savings by 2027 2.
  • The shift began when Lumen brought Palantir’s tools into its own operations, then later teamed up to sell joint products to enterprise customers 3.
  • Demand from large AI firms backed the move, including a contract to expand Anthropic’s fiber network 4.
  • Those deals helped Lumen land debt rating upgrades and recast itself from a legacy telecom provider to a digital infrastructure company 4.
