You have a Linux EC2 web server instance running inside a VPC. The instance is in a public subnet and has an EIP associated with it so you can connect to it over the Internet via HTTP or SSH. The instance was also fully accessible when you last logged in via SSH and was also serving web requests on port 80. Now you are not able to SSH into the host nor does it respond to web requests on port 80 that were working fine last time you checked. You have double-checked that all networking configuration parameters (security groups route tables, IGW, EIP. NACLs etc.) are properly configured and you haven’t made any changes to those anyway since you were last able to reach the Instance. You look at the EC2 console and notice that system status check shows “impaired.” Which should be your next step in troubleshooting and attempting to get the instance back to a healthy state so that you can log in again?
