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.
