最近上海 CN2 去日本的线路问题

This topic created in 3837 days ago, the information mentioned may be changed or developed.

5 天前开始察觉到速率有所变化，现在出口峰值最高只有 150Mbps ，以前能够稳定跑满
然后随意 traceroute 了一下大部分常去的日本 ip ，

如上所示，基本在第十跳的时候会走一遍香港，然后再去日本，而不是像以前那样直接走日本
我想速率的影响问题，可能出现在这里。
还好最高速率并没有太差，对速度不敏感的话，基本不成问题，但一直走香港总不是件事情。这两天我估计是 CN2 上海至日本那段可能 down 了？

有用 CN2 的各位要不都来检查一下是不是这样？我看最近大家都在反映 CN2 线路出问题的事情
