今天早上刚想打开网站看看，发现浏览器返回ERR_CONNECTION_TIMED_OUT。

然后我马上就去测试服务器了，步骤如下。

1、 ssh：

 ssh: connect to host xxx.xx.xxx.xxx port 22: Operation timed out

2、 ping

 Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
Request timeout for icmp_seq 4
Request timeout for icmp_seq 5
Request timeout for icmp_seq 6
Request timeout for icmp_seq 7
Request timeout for icmp_seq 8
Request timeout for icmp_seq 9
Request timeout for icmp_seq 10

3、 traceroute

看到traceroute最后一步，查了42.120.240.17已经到了阿里巴巴了。。。 问题是出在这么？

服务器都登不上去了，我现在还想不出来有什么办法去解决。

各位能帮忙看看么？谢谢了。
