[CentOS] Please remove mirrors.skyshe.cn from mirror list,Thanks!

Hi,
     This is a (new?) mirror in China, but I found this mirror hasn't 
enough bandwidth, I have tested in many server in China, this mirror has 
a low ping (smaller than 30ms), and a very low download speed(smaller 
than 10KB/s), so fastestmirror will let it to be the best mirror, but 
download very slow.
     I am really happy to see that skyshe.cn is willing to provide this 
service. However, I don't think their bandwidth is enough to handle this 
service.

Tom
