Please delete the custom Host record

Since the IP assigned by CDN is blocked, in order to take into account the user experience of most people, CDN is temporarily closed. Users who have made IP optimization are requested to delete the custom Host record.
Users who use backup servers, please also use the main server. Now that CDN is closed, there should be no need to use the backup server.

After turning off the security protection provided by CF, the risk faced by the site will increase significantly. After solving the problem of being blocked, it is not ruled out that it will continue to be added in the future.
