ABOUT Fastly

Fastly is a global content delivery network (CDN) that allows content to deliver faster, and reduces latency by moving the content closer to where the user is located.

The Fastly edge cloud platform includes its content delivery network (CDN), image optimization, video and streaming, cloud security, and load balancing services.


Fastly does not work in China because it has no CDN POPs in China.

If a site uses Fastly in China, they likely rely on Fastly’s “Near-China” CDN POPs. As with most “Near-China”, sites using Fastly in China are slow and unstable, as shown below. Resulting in a poor user experience for visitors in China.
