Investigating

AWS making progress on resolving the issue with new EC2 instance launches in the US-EAST-1 Region and are now able to successfully launch new instances in some Availability Zones. We are applying similar mitigations to the remaining impacted Availability Zones to restore new instance launches. As we continue to make progress, customers will see an increasing number of successful new EC2 launches. We continue to recommend that customers launch new EC2 Instance launches that are not targeted to a specific Availability Zone (AZ) so that EC2 has flexibility in selecting the appropriate AZ.
