These details describe recent network behavior. A watchlist or old report can tell us what to test, but it cannot create a current result.
How access is controlled
China's Great Firewall
China filters traffic moving between domestic networks and the wider internet. The system can affect website lookups, secure connections, and network addresses, but results still vary by provider and location.
Access may differ by provider, region, and connection method. We only show a warning when recent measurements for China support it.
Why the answer can change
Internet access is not one global switch.
Your network matters
Home, mobile, work, and school networks can apply different rules.
Your location matters
A result in one city or country may not describe another place.
The time matters
Restrictions and outages can begin or end quickly, so freshness stays visible.
Simple answers
Questions people ask
Does “no strong signal” mean Signal works everywhere in China?
No. It only means the recent checks available for this country did not cross the warning threshold.
Why might Signal work for one person but not another?
People may use different providers, locations, connection methods, or versions of the service.
Do old blocklists decide this answer?
No. Lists help choose what to check. Only recent network measurements can support the result shown here.
