I am the mirror's admin at Nanjing university of Posts and Telecommunications,i also announced this mirror -'mirrors.njupt.edu.cn' before, and it shows in the http://mirror-status.centos.org and it looks ok,i can get other machines to update using this mirror automatically in my school before ,but now it doesn't show in the mirror list ,when i use the yum fastest mirror plugin ,is there anyway to correct this problem or is there anyway to better match this mirror in my school .When I registered this mirror in fedora mirror list ,it shows me that you can set some ip blocks that my school uses. -------------- next part -------------- An HTML attachment was scrubbed...
