Upgrading the Cloudflare China Network: better performance and security through product innovation and partnership

Cloudflare has expanded its presence in China through a partnership with JD Cloud, the cloud division of Chinese internet giant JD.com. The company's new China Network built on JD Cloud's infrastructure offers significant performance and security improvements compared to the previous in-country network. Key innovations include serving DNS inside China for faster response times and improved reliability, as well as mitigating DDoS attacks within the country through edge-based mitigation systems and remote signaling to Chinese ISPs. These advancements have resulted in a 30% performance boost for customers using Cloudflare's services in China.
