why our site url Is not listed in the table http://www.centos.org/download/mirrors/ ?

but in http://mirror-status.centos.org/#cn

our site is http://mirrors.cug.edu.cn/

The list on the webpage lists only up-to-date mirrors. As of this writing, http://mirror-status.centos.org/#cn says mirrors.cug.edu.cn has been updated 3.1 days ago, which is too old. Please make sure your mirror is syncing properly from msync.centos.org. Once your mirror is up to date, it will get listed on the download mirrors page again.
