前幾天其實寫過KT美國，100M獨享，不限流量的機器測評，http://www.xjxyb.com/981.html，今天再次驗證了下，對電信來講，確實是雙向cn2，平時其實沒有把這個cn2當做賣點，只是說優化線路。399元1月的美國cn2獨立服務器，100M獨享，還是非常超值的，配置看標題即可，雙路L5420/8G內存/500G磁盤/100M獨享/流量不限，下單地址：https://www.eeqiu.com/cart.php?a=add&pid=44

1、ping.chinaz.com情況。

2、回程路由情況，比如KT美國到廣東電信，北京聯通，北京移動路由情況。

3、去程路由情況，比如深圳電信到美國KT路由，走cn2.

4、superbench情況，可以觀察cpu型號，內存大小，磁盤大小，以及帶寬情況。
