Unable to Access http://ww.wp.xz.cn/news/feed/

Hi there,

For some reason I’m unable to access “http://ww.wp.xz.cn/news/feed/” from one of my web servers, even though I can access “http://ww.wp.xz.cn/” just fine from that particular server.

Is it possible that my server’s IP address had been blocked from accessing the feed by wordpress? If so, is there any way to get it unblocked?

Thanks.
