Does PageSpeed Insights Work in China? The Mainland Blind Spot a Green Score Hides
PageSpeed Insights is a fine global tool, but it measures from Google's own servers and a narrow slice of opted-in Chrome users — not from inside mainland China. A passing score can't tell you whether your site actually works there. What does: a measurement taken from inside the mainland, plus the compliance gate — an ICP filing on your public site and PIPL for any China visitor data. In Google's own words and China's own law.

Does Firebase Work in China? Data Residency, PIPL & Google's Missing China Region

Does SAP Cloud Platform (BTP) Work in China? Data Residency & the Two Paths
SAP Cloud Platform — now SAP Business Technology Platform (BTP) — runs across global regions on AWS, Azure and Google Cloud that keep your enterprise and personal data offshore, and separately inside a China (Shanghai) region on Alibaba Cloud reached through a dedicated China entry point. The two paths, in SAP's own documentation and China's own law: data residency and PIPL on a global region, versus a China region that turns on an ICP filing and a China entity for a public site.

Does Oracle Cloud Work in China? ICP, Data Residency & an Offshore Cloud

Liferay DXP is open-source software you can self-host or run on Liferay's managed SaaS/PaaS cloud, so "does it work in China" is really "where does it run." Self-hosted, the door is your host's ICP filing; on Liferay's cloud — whose data centers include no mainland region — it's PIPL data residency for the portal and user data it holds, in Liferay's own words and China's own law.
