Website access in China
What websites are blocked in China?
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.
How it works
China's Great Firewall
The world's best-known national filtering system.
Traffic passes through filtering points
Connections between China and the wider internet can be checked at major network gateways.
Different connections can be interrupted
A website lookup, its network address, or the start of a secure connection may be affected.
One test never tells the whole story
A result can differ by provider, city, connection method, and time of day.
Access may differ by provider, region, and connection method. We only show a warning when recent measurements for China support it.
