CLOUDFLARE’S network recently crossed 500 terabits per second (Tbps) of external capacity, a milestone described as 500 Tbps of capacity: 16 years of scaling our global network. According to The Cloudflare Blog, this figure represents total provisioned external interconnection capacity—the sum of every port facing a transit provider, private peering partner, Internet exchange, or Cloudflare Network Interconnect port across 330+ cities, not peak traffic.
The piece notes the company started in 2010 from a small office in Palo Alto and has since expanded to 330+ cities and 125+ countries, protecting more than 20% of the web. It also highlights notable defence capabilities, including a 31.4 Tbps DDoS attack mitigated in 2025 lasting 35 seconds, without human intervention, and states that sixteen years of architectural decisions underpin the ability to drop attack traffic at line rate across all servers. The article frames this scale as a foundation for continued growth and invites further peering and collaboration with network operators.
