Microsoft Ajax CDN in China: Addressing Web Delivery Challenges
Exploring the challenges of Microsoft Ajax CDN in China and how 21YunBox's solutions ensure efficient web content delivery.
Does Microsoft Ajax CDN work in China?
Microsoft's Ajax CDN completed every attempt from mainland China. Measured fact: from a probe inside mainland China (Alibaba Cloudcn-zhangjiakou), three runs, 2026-08-29, three of three runs completed, first byte in a median 882ms and paint at 3.9s. Put against the rest of this census, a clear picture emerges rather than a rule: this host and cdnjs completed every run, while Google Hosted Libraries, BootstrapCDN and Font Awesome completed none. Two of five public asset hosts worked. That is why the advice is to measure the specific host you depend on — and why bundling the library into your own build, which removes the question, is usually cheaper than choosing between them.

Why some public script CDNs work in China and others do not
In China, Microsoft Ajax CDN users often encounter speed and loading problems related to the compatibility of the service with local internet systems. The Great Firewall significantly affects the performance of international CDN services, leading to latency and accessibility issues.
