Which CDNs actually have points of presence inside mainland China, which serve China from Hong Kong or Singapore, and which require you to hold an ICP filing yourself. A provider-by-provider comparison.
Your Shopify store is reachable from mainland China, but Shopify hosts your storefront and checkout on its own offshore infrastructure with no mainland-China region — so the real doors are the ICP filing a public store needs and the PIPL cross-border transfer of your shoppers' personal and order data. A compliance-first look, in Shopify's own words and China's own law.
Netlify is an excellent global host and edge network, with no node inside mainland China. Serving a public China audience means clearing two independent gates — an ICP filing bound to a licensed in-country host, and a PIPL-aware way to handle visitor data at the border — not just making the site faster. How Netlify and 21YunBox fit together, in Netlify's own words and China's own law.
Your Vercel app stays on Vercel — it's an excellent global origin. A public mainland-China audience additionally needs an ICP-filed, in-country presence Vercel's global edge isn't built to hold, plus a PIPL-aware way to handle visitor data at the border. How Vercel + 21YunBox fit together — in Vercel's own words and China's own law.
Heroku runs no region inside mainland China — its Common Runtime is the US and Europe, its Private Spaces a fixed set of offshore AWS regions — so a China-facing Heroku app is served offshore with no ICP-filing footing, and your users' personal data lands outside the mainland under PIPL. A compliance-first look at the two doors.
Heroku is a platform-as-a-service that runs on offshore AWS regions — its Common Runtime offers only Europe and the United States, and no Heroku region is inside mainland China — so a China-facing app is served offshore with no ICP-filing path, and the personal data your dynos and database hold lands outside the mainland under PIPL. A compliance-first look at the two doors.
GitHub is a great place to build and ship a static site — but a public, mainland-China audience turns on two things GitHub Pages' offshore hosting can't provide: an ICP filing tied to a licensed in-country host, and reliable reachability inside the mainland, where github.io is often blocked or throttled. How GitHub + 21YunBox fit together — in GitHub's own words and China's own law.
Sanity serves your editorial content from Google Cloud data centers in the EU and a global API CDN with no mainland-China point of presence, so fetching it live from inside China is a delivery risk — while the ICP filing and PIPL duties that decide legality sit on the site that embeds Sanity, not on the CMS. An honest, compliance-first look.
Cloudinary is a fine global media platform — but "does it work in China" is a compliance question, and mostly it isn't Cloudinary's to answer. The ICP filing sits on your public mainland site; your China users' uploaded media (faces are personal information) stored offshore brings PIPL's cross-border rules into play; and reaching the mainland at all is a separate Enterprise add-on. Weighing Cloudinary or any alternative on the axis that actually decides whether you may operate — in Cloudinary's own words and China's own law.
Gatsby Cloud has been sunset: Netlify, which acquired Gatsby, moved existing sites onto its own platform, while Gatsby the open-source framework lives on. So the real question isn't how to speed up Gatsby Cloud — it's how a Gatsby site, hosted elsewhere now, lawfully serves mainland China. That turns on two gates its new host can't clear alone: an ICP filing, and a PIPL-aware way to handle visitor data at the border — in the vendors' own words and China's own law.
Surge.sh publishes your static site to its own offshore CDN, so whether it "works in China" is a reachability and ICP question, not a speed trick. Served cross-border with no mainland region, a public mainland site also needs an ICP filing an offshore host can't hold — in Surge's own words and China's own law.
