Instances Missing

If your instances are missing from the AWS Management Console in the ap-southeast-1 region, there are a few steps you can take to try to resolve the issue:

1. Verify the region: Make sure that you are in the correct region (ap-southeast-1) in the AWS Management Console.
2. Check the instances' state: Go to the EC2 Dashboard and check the state of the instances. If they are in a stopped state, you can start them from the AWS Management Console.
3. Check the VPC: Make sure that the instances are in a VPC and that the VPC is correctly configured and has the correct subnets, security groups, and network ACLs.
4. Check the network interfaces: Make sure that the network interfaces are correctly associated with the instances and that they have the correct private and public IP addresses.
5. Check the instances' tags: Make sure that the instances have the correct tags and that the tags are correctly associated with the instances.
6. Check the instances' visibility: Make sure that the instances are not hidden from the console due to the "AWS Management Console" tag value.
7. Contact AWS Support: If you are still unable to find your instances, you can contact AWS Support for further assistance.

Note: These steps are applicable to instances running on a Windows platform.
