如何解决南电信北网通跨网访问web速度问题?看了一下新浪
公司的web服务器在上海电信机房,在全国各地的访问速度不均,北方的用户比较慢,有时北京的adsl用户基本不能访问。
应该是电信,网通跨网的问题。
想解决这个问题,就看了一下新浪的web站点,以为他们用的是CDN,但这玩意很贵的。
nslookup了一下www.sina.com.cn,结果如下:

随便看看其中一台http://61.135.152.73/:得到:

哦,原来他们用的是[color=red:ac3ab19ce9](squid/2.5.STABLE5)[/color:ac3ab19ce9] ,估计是做web反向代理。
但看他们的IP,也是连续的网段,肯定要么在网通,要么在电信,那为什么各地访问sina都比较快呢?
求教??
