Most importantly, it is unwise to host a website (in terms of port 80/443) in China and aim to serve outside world. You should host a typical server outside China, and tunnel the server inside China (for sync).
ic, we checked, seem if don't have any ICP , seem china will shut down the web site, mean cannot access inside china too,but our china user can access.
because not all HK ISP cannot go, only some HK ISP cannot.
anyway, will check this.
