Does KeyCDN work in China?
KeyCDN completed every attempt from mainland China, with a first byte over a second. Measured fact: from a probe inside mainland China (Alibaba Cloudcn-zhangjiakou), three runs, 2026-08-28, three of three runs completed, first byte in a median 1,177ms and paint at 2.0s. For a CDN measured from inside China, that first byte is the finding: a content delivery network without points of presence inside the mainland is delivering across the border like any other origin, and the acceleration it provides elsewhere does not transfer. Delivering from inside is a different arrangement, and it carries the ICP filing. What we measured for KeyCDN from inside China

What KeyCDN delivery looks like from inside China
Despite its global efficiency, KeyCDN faces unique challenges in China, primarily due to two reasons: speed/loading issues and legal/compliance complexities.
Speed and loading problems in China often stem from compatibility issues with local internet infrastructure. Chinese internet policies and the Great Firewall significantly affect how data is transmitted within and outside the country. This results in slower load times and potential accessibility issues for KeyCDN users. Moreover, KeyCDN’s global network, although extensive, faces limitations in China due to regulatory restrictions and the need for partnerships with local CDN providers.
Legal and compliance challenges in China are another significant hurdle. The Chinese government enforces strict internet regulations, requiring foreign companies to comply with local laws for data storage, content regulation, and user data privacy. Failure to adhere to these regulations can lead to service interruptions or legal consequences. Services like AWS, Google Cloud, and Azure also face similar compliance challenges in China. For detailed information on their compliance policies, refer to their official documentation.

KeyCDN’s network boasts an impressive number of Points of Presence (PoPs) globally. However, its presence in mainland China is limited, primarily operated through partnerships with local providers to navigate the complex regulatory landscape.
