AWSもまだまだ不安定かも

EC2のサーバが吹っ飛んだ。
インスタンスの故障ってよくあることでしょうか？

故障したときはこんなメールが飛んできました。

Hello,
We have noticed that one or more of your instances are running on a host degraded due to hardware failure.
   **********（インスタンスのID）
The host needs to undergo maintenance and will be taken down at 12:00 GMT on 2011-05-16. Your instances will be terminated at this point.
The risk of your instances failing is increased at this point. We cannot determine the health of any applications running on the instances. We recommend that you launch replacement instances and start migrating to them.
Feel free to terminate the instances with the ec2-terminate-instance API when you are done with them.
Sincerely,
The Amazon EC2 Team

現在復旧中。

クラウドサービスは一極集中は危険。
AWSでは1インスタンスに依存しすぎるのも危険。
ちょっと手間が増えるけど仕方ないかな。
