一个上游是cera的4837优化线路，我连接服务器和ping服务器都正常，ssh连接也正常。
但是从vps访问其他网站就时不时啥也连不上，这到底是啥问题啊，有点摸不着头脑。 人家封了你IP有什么奇怪的 [*]root@wiki-4837-pre:~# ping 1.1.1.1
[*]PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
[*]64 bytes from 1.1.1.1: icmp_seq=1 ttl=55 time=0.806 ms

[*]64 bytes from 1.1.1.1: icmp_seq=4 ttl=55 time=0.782 ms

[*]ping 1.1.1.1 也是有回复的。

但是这个是不定时的，一会能通，一会不能通。
