Signal answered our probe, but measures as unreachable from mainland China.

Volunteers running OONI on Chinese networks recorded 477 anomalous results in 596 tests (80%) between and .

Our own probe runs from one region outside China, so it cannot see this. If you are in China and it will not load, the service is most likely fine and the network in between is not.
