when check web page network status in chrome developer tools, I found nearly every elements from mirrors.skyshe.cn with load latency more than 1second, avg to 2s, in morning 7:30.

I think its network is just fine for China Telecom user. Over sea users may fell slow speed is possiblely due to policy of China Telecom. Users from other ISPs in China may experience slow speed too.

But this site may have heavy IO load problem. In its homepage http://mirrors.skyshe.cn/, nearly every schedule of rsync fail or stop since 2014-11-12.

Ideally more tests should be done from China.

Did a few wgets from England and Romania, can confirm Tom's complaint, got ~20 KB/s.

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.
