6月3日，已经驻扎在东京将近两年的主机开始抽风了，这种抽风以前真的没有发现过，virtual private network 果断一个也连接不上了，甚至putty完全没有响应，报错Error Network，Connection timed out.

果断联系linode提供商，

Hello,

I’m sorry to hear of the connectivity issues you are experiencing. So that we may further investigate this issue, could you please provide the output of “mtr –report” from your location to your Linode, as well as the reverse? More information on generating and interpreting MTR reports can be found in the Linode Docs:

然后使用mtr来测试主机，从国内几个地点测试到东京的连接情况，大致相同。对方给的回复

Hi there,

All of this is a classic issue with the GFW Please notice how the packet loss starts at the 202 hops and persists all the way out to the server; this is evident of the deep packet inspection stage that the GFW goes under before you’re completely blocked.  Would you like for us to switch your IP again? This is really the only course of action that works when faced with this issue.

果真是碰上某个敏感的日子了，你懂得：） 依稀记得两年前，google也是在此时渐渐淡出了人们的视线，真是无奈呢

linode给我换了几个IP address, 测试结果几乎没有改善。看样子东京的服务器大部分都遭殃了。

最后果断建议换到美国的数据中心，一路折腾到6月5日

从这里可以测试各个数据中心，似乎美国的几个地区比东京的还要给力https://www.linode.com/speedtest

Fremont坐落在旧金山湾区，似乎是中国朋友的较好选择。关于这方面的问题，欢迎找我交流。
