最近，互联网上最大的事可能是Amazon的AWS宕机了，而且好几天都没有完全恢复。整个Internet都在讨论这个事，Internet很不高兴，后果可能很严重。可能是因为这个事件对中国没有影响，所以中文这边相关的文章不多，大家可以参考一下和讯网的这篇《伤不起！亚马逊史前最大宕机事件的启示》。

国外有人把所有和这个事件相关的贴子都收集了起来，都是一些相当不错的贴子和文章，尤其是一些经验教训的贴子，很受教，转给大家看看。这个贴子的来源在这里。

Recovering from Amazon cloud outage by Drew Engelson of PBS.

PBS was affected for a while primarily because we do use EBS-backed RDS databases. Despite being spread across multiple availability-zones, we weren’t easily able to launch new resources ANYWHERE in the East region since everyone else was trying to do the same. I ended up pushing the RDS stuff out West for the time being.  From Comment
