Dear Amazon EC2 Customer,
One or more of your Amazon EC2 instances in the us-east-1 region requires important security and operational updates which will require a reboot of your instance. A maintenance window has been scheduled between Wed, 3 Jan 2018 00:00:00 GMT and Wed, 3 Jan 2018 17:00:00 GMT during which the EC2 service will automatically perform the required reboot. During the maintenance window, the affected instance will be unavailable for a short period of time as it reboots. You may instead choose to reboot the instance yourself at any time before the maintenance window. If you choose to do this, the maintenance will be marked as completed and no reboot will occur during the maintenance window. For more information on EC2 maintenance please see our documentation here:
https://aws.amazon.com/maintenance-help/. More details on rebooting your instances yourself can be found here:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-reboot.html
To see which of your instances are impacted please visit the 'Events' page on the EC2 console to view your instances that are scheduled for maintenance:
