Fastly is a developer‑friendly edge cloud platform offering CDN delivery, image optimization, streaming, and edge compute via its Varnish‑based edge network. Designed for high‑frequency, dynamic content, Fastly provides instant config activation, real‑time logging, and developer APIs. It integrates with modern web frameworks and supports custom logic at the edge via Compute@Edge.

Fastly is partially available in China, but with inconsistent performance. Its global POPs aren’t in mainland China, and traffic must traverse international links, leading to high latency and intermittent failures due to GFW interference or throttling. This makes it unsuitable for performance‑critical or interactive sites aimed at Chinese users. Developers often self‑host static assets in Chinese CDNs like Alibaba CDN, Tencent Cloud CDN, or use mirror services via BootCDN. For edge logic, Fastly’s Compute@Edge cannot execute within mainland China. As a result, Chinese users are typically redirected to locally hosted resources to ensure consistent performance.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
