8. Summary
Return-to-China latency is high, and the route is no longer what it used to be. It includes DDoS protection and has weak performance, making it suitable as a reverse-proxy or low-performance website box. Speed may not match an optimized CDN, but it is cheap, right? There is no forever heirloom after all
