各位有在用AWS先進前輩，有沒有遇過跟我一樣的情況，一月初其實就有收到一樣的通知，我的處理方式是原EC2建立AMI創建新的實例套用剛建的那個AMI，但這樣做有個缺點就是內網的IP會跟著異動，該實例是已上線的中斷服務以及異動內網需做的設定比較多。

然而這個月又收到一模一樣的通知，也就是間隔一個月。

我想請教的是，這是不是AWS在提醒我要換更高階的主機(現行的主機都有控制在使用資源不會超過 50%，也沒有狀態檢測出現錯誤)。

另一個問題是 我是不是能把實例重啟就好，不需要整個重建，他給的提示讓我不太確定是要重啟還是重建。

在此先感謝看完本文的先進前輩，福服各位虎年行大運。

以下是AWS 針對此通知的描述
EC2 has detected degradation of the underlying hardware hosting your Amazon EC2 instance associated with this event in the ap-southeast-1 region. Due to this degradation your instance could already be unreachable. We will stop your instance after 2022-02-17 06:00:00 UTC. Please take appropriate action before this time. You can find more information about retirement events scheduled for your EC2 instances in the AWS Management Console https://console.aws.amazon.com/ec2/v2/home?region=ap-southeast-1#Events

• What will happen to my instance? Your instance will be stopped after the specified retirement date. You can start it again at any time after it's stopped. Any data on local instance-store volumes will be lost when the instance is stopped or terminated. * What do I need to do? We recommend that you stop and start the instance which will migrate the instance to a new host. Please note that any data on your local instance-store volumes will not be preserved when you stop and start your instance. For more information about stopping and starting your instance, and what to expect when your instance is stopped, such as the effect on public, private and Elastic IP addresses associated with your instance, see Stop and Start Your Instance in the EC2 User Guide (https://docs.aws.amazon.com/en_us/AWSEC2/latest/UserGuide/Stop_Start.html ). However, if you do not need this instance, you can stop it at any time yourself or wait for EC2 to stop it after the retirement date. * Why is EC2 retiring my instance? EC2 may schedule instances for retirement in cases where there is an unrecoverable issue with the underlying hardware. For more information about scheduled retirement events please see the EC2 user guide ( https://docs.aws.amazon.com/en_us/AWSEC2/latest/UserGuide/instance-retirement.html ).
