近期两次由光纤维护引发的 GCP 宕机事件

GCP 最近两次宕机都归因于“光纤维护”。8 月 20 日 us-west1 区域宕机时，他们表示 [1]：
> 中断源于计划内的光纤维护，该维护意外地削弱了 us-west1 区域内数据中心之间的网络容量。
然后，在 9 月 1 日 us-central1-b 区域（以及其他区域的附带影响）宕机时，他们表示 [2]：
> 此事件的直接技术触发因素是在例行的硬件维护过程中，意外物理断开了网络光纤跳线。
不确定这两次事件是否相关，但据称在第一次事件后，程序已显著更改以防止第二次事件发生。

Both of GCP's recent outages were caused by "fiber optic maintenance". On August 20th when us-west1 went down they said [1]:<p>> The disruption originated during scheduled fiber optic maintenance, which unexpectedly compromised network capacity between data centers within the us-west1 region.<p>Then on September 1st when us-central1-b (and collateral affects in other zones) went down they said [2]:<p>> The immediate technical trigger for this event was the inadvertent physical disconnection of network fiber-optic cables during a routine hardware maintenance procedure.<p>Not sure if they're related but apparently procedures we're significantly changed after the first incident to prevent the second incident.<p>[1] https://status.cloud.google.com/incidents/utF3FMFdQfwBzJcGG6vf
