CN2 Acceleration Pitfall Guide: Say Goodbye to Asymmetric Detours and Scrubbing Downgrades, Build a Three-Network Direct-Connect High-Defense Edge Arc

This article breaks down common CN2 acceleration pitfalls—one-way CN2, fragmented China Telecom/Unicom/Mobile experience, and routes forced to US scrubbing after DDoS attacks—and explains how to build a secure, high-speed CN2 China acceleration architecture via CNAME without migrating your origin server, covering bidirectional routing, three-network direct connectivity, attack-time acceleration stability, and protocol stack optimization.
