BGP is vulnerable to routing hijacks and path leaks that negatively impact traffic on the Internet. RPKI helps solve some of these problems, but for some forged paths, we need to rely on a simpler mechanism: First AS enforcement in BGP.

The first quarter of 2026 saw a surge in Internet disruptions, from nationwide shutdowns in Uganda and Iran to unprecedented drone strikes on cloud infrastructure. We explore the data behind these events using Cloudflare Radar.

Cloudflare’s global network has officially crossed 500 Tbps of external capacity, enough to route more than 20% of the web and absorb the largest DDoS attacks ever recorded.

ASPA is the cryptographic upgrade for BGP that helps prevent route leaks by verifying the path network traffic takes. New features in Cloudflare Radar make tracking its adoption easy.
