RPKI Now Protects 70% of Internet Routes, Up from 54% a Year Ago

RPKI (Resource Public Key Infrastructure) protection of internet routes has surged to 70.3% of routed prefixes in September 2026, up from 54% a year earlier—a 30% increase driven largely by China's adoption. RPKI cryptographically validates routing announcements to prevent traffic from being misdirected to wrong networks, addressing vulnerabilities like the 2008 incident where Pakistan Telecom accidentally redirected YouTube globally. The sharp acceleration in adoption demonstrates that RPKI is effectively preventing invalid routes from propagating across the internet while accounting for less than 1% of BGP updates.
