Cloudflare's global network and backbone has reached a major milestone, crossing 500 terabits per second (Tbps) of external capacity. This represents the total provisioned external interconnection capacity across Cloudflare's 330+ data centers worldwide. The company has grown from a small office in Palo Alto in 2010 to now protecting more than 20% of the internet, with the ability to mitigate massive DDoS attacks of over 31 Tbps without human intervention.

Why it matters

Cloudflare's network growth and scaling demonstrates the company's ability to build critical internet infrastructure that can handle the increasing demands of modern web traffic, including the rise of AI-powered crawlers and autonomous agents. As the internet continues to evolve, Cloudflare's network is positioned to provide reliable, secure, and high-capacity services to a growing portion of the web.

The details

Cloudflare's network has expanded city-by-city over the past 16 years, from a single transit provider in Palo Alto to over 330 data centers in 125+ countries today. Along the way, the company has had to navigate challenges like missing hardware, customs strikes, and even dental floss issues during rapid expansions. As the network grew, Cloudflare also expanded its services beyond just website caching, offering security, enterprise networking, and developer platform capabilities that run on the same global infrastructure.

  • Cloudflare launched from a small office above a nail salon in Palo Alto in 2010.
  • In 2018, Cloudflare opened 31 new data centers in 24 days, from Kathmandu to Reykjavík.
  • In 2025, Cloudflare mitigated a 31.4 Tbps DDoS attack lasting 35 seconds, without any human intervention.
