My all data disappeared

If your instances and applications are running but aren't appearing in your AWS Console, there are a few things to check:

Region: Double-check that you're viewing the correct AWS region. Account ID: Confirm you're logged into the correct AWS account. Sometimes users accidentally switch accounts (e.g., between personal and organization accounts). Permissions: Ensure you have the permissions required to view EC2 resources in the AWS Management Console. Billing/Quota: Check your AWS account for any billing or quota issues that may affect visibility.

if the above doesn't work. Kindly open a ticket to AWS Support team

Thanks

    If your EC2 instances and applications are still functioning but not visible in the AWS console, there are a few potential explanations and steps you can take:

    1. Double-check your region: Even though you're sure you're in the correct region, it's worth verifying again. EC2 instances are region-specific, so ensure you're looking in the right place.

    2. Clear browser cache and cookies: Sometimes, browser-related issues can cause display problems in the AWS console. Try clearing your browser cache and cookies, then log in again.

    3. Use EC2 Global View: This feature allows you to see EC2 resources across all regions. Access it from the EC2 dashboard to check if your instances are visible there.

    4. Check for filters: Ensure no filters are applied in the EC2 dashboard that might be hiding your instances.

    5. Verify account status: If there were any issues with your AWS account, such as billing problems, it could affect the visibility of your resources in the console.

    6. Check CloudTrail logs: If available, review CloudTrail logs for any events that might explain the disappearance of your instances from the console view.

    7. Contact AWS Support: If none of the above steps resolve the issue, reach out to AWS Support for assistance. They can help investigate why your resources are not visible in the console despite being operational.

    Remember, if your applications are still working and you can connect to your instances, your data and resources likely still exist. This suggests the issue is more likely related to the console display rather than actual resource deletion.
