发现一个小秘密哦，长见识了。
如果你继续，host 大公司各国的当地域名，你会发现,自由的互联网，只是个传说。

把他漏贴了。

看出来了吗？如果多host 一些大公司的域名，会很好玩的哦，不光是中国哦，别的国家一样。如果你去一些敏感的域名，那就更有意思了。

google.cn有单独的服务器，原因不言而喻，这个也不是什么新闻了，剩下的其他国家好像使用的全是google总部的数据库。—— 不知道我的理解对不对？

对呀，但是要提醒一下，不同的国家对大公司采取不同的管理哦，比如a国要求XX公司特殊管理，对xx1可能一般了，b国要求XX公司一般了，对xx1就特殊了，很复杂的。中国之所以有名，是因为太多了和太明显了，老美就悄悄的多了，很多人都没有感觉到。你想想很多知名的黑客，为什么不在美国呆着，因为不自由呀。
