Fastly is a company that provides a content delivery network (CDN) and cloud services platform. A CDN is a network of servers that are distributed around the world and are designed to deliver web content to users more quickly and efficiently.
Fastly’s CDN is used by businesses and organizations to improve the performance and availability of their websites and applications. For example, when a user accesses a website that is powered by Fastly, the content is delivered to them from the server that is physically closest to their location, which can help reduce the time it takes for the content to load. Here are some websites using fastly, such as askubuntu.com, getbootstrap.com, and Github.
In addition to its CDN, Fastly also provides a range of other cloud services, including security, load balancing, and monitoring tools. These services can help businesses and organizations improve the reliability, scalability, and security of their online presence.
Overall, Fastly is a useful tool for businesses and organizations that want to improve the performance and availability of their online content and applications, and make them more reliable and secure.
Is Fastly blocked in China?
No. Fastly is not blocked in China, but it’s unstable and could easily be blocked by the Ministry of China. Suppose you want to use Fastly CDN in China (inside the Great Firewall of China). Like many other Global CDN providers such as Cloudflare or Akamai, the recommended approach is to get the ICP Filing or License (the legal permit to host in China) for your site to host legally in China.
