Does Contentstack work in China?
Contentstack produced the slowest paint of any site that never completed a single run and still never finished. Measured fact: from a probe inside mainland China (Alibaba Cloudcn-zhangjiakou), three runs, 2026-08-28, none of the three runs completed within 60 seconds, first byte in a median 1,104ms and a largest-contentful-paint of 28.0 seconds. A 28-second paint is not a number a visitor waits for; it is a number that exists only because a measurement tool kept waiting. For a headless CMS the delivery question is separable from the authoring one — your front end can be served from inside China while the content API stays where it is — but the API round trip is then paid on every render.

What we measured on Contentstack from inside China
Over 90% of websites using Contentstack take 30+ seconds to load in China and are missing 25%+ of their media content. Meaning if your visitors in China don’t bounce after a 30+ second load time, many of the sites images or videos will be missing.
There are two main reasons Contentstack does not work in China:
-
Contentstack is not compliant with China’s laws and regulations.
-
Contentstack does not have any servers or CDNs in China. Content delivered with Contentstack either won’t open or will be extremely slow in China.
To show you, we ran a speed test on a media asset delivered to China using Contentstack.
As you can see, the speedtest shows that the Contentstack delivered asset is extremely slow in China, mostly red,orange, and yellow.
