主要问题是：除 baidu.com 搜索外
*.baidu.com 均二级域名无法打开
如 pan.baidu.com/zhidao.baidu.com
tracert 明显已经过墙了

nslookup pan.baidu.com
Server: 75.75.75.75
Address: 75.75.75.75#53

Non-authoritative answer:
pan.baidu.com canonical name = yiyun.n.shifen.com.
Name: yiyun.n.shifen.com
Address: 180.149.145.241


traceroute to yiyun.n.shifen.com (180.149.145.241), 64 hops max, 52 byte packets
