Is it only me but I can't access the Cesium forum from this url : http://cesiumjs.org/forum.html ?
Do you come from China？

Nop, I'm in France. Why?
The website forum seems to be working fine (at least on the multiple devices I’ve tried). What kind of error are you getting? Can you get to https://groups.google.com/forum/?fromgroups#!forum/cesium-dev directly?
I imagine the question was due to the fact that China blocks Google Groups, which is where the forum is hosted.
