My ec2 instance is stuck in the "Shutting-down" state for more than 18 hours

I understand you're experiencing a persistent issue with an EC2 instance stuck in the "shutting-down" state. Since you've already attempted the standard troubleshooting steps including force termination through the console, the next step is to escalate this to AWS Support.

Based on the troubleshooting guidance for stuck instances, when force termination fails to resolve the issue, you should:

1. Request help on AWS re:Post - You can post your issue there for community assistance
2. Create a technical support case in the AWS Support Center - This will allow AWS Support engineers to investigate the underlying issue with your instance

Since your instance has been stuck for over 18 hours and standard remediation steps haven't worked, this likely indicates an issue with the underlying host computer that requires AWS intervention to resolve.

Important note: You will not be charged for instance usage while your instance is in the "shutting-down" state or any other state except "running," so there's no cost concern while this issue is being resolved.

When you contact AWS Support, provide them with:

• Your instance ID (i-0de88c9d5d4445e73)
• The timestamp when it became stuck (2026-03-23 23:56:36 GMT)
• The troubleshooting steps you've already attempted

AWS Support will have the tools necessary to investigate and resolve the underlying issue preventing your instance from completing the termination process.
