Create a New Default VPC using AWS Console or CLI

Amazon Virtual Private Cloud (VPC) now allows customers to create a new default VPC directly from the console or by using the CLI. With this release, customers no longer need to contact AWS support if the default VPC has been deleted, as they can create a new default VPC by using this self-service feature. Customers can also take remedial actions against accidental deletion of default VPCs, by automating creation of a new default VPC using the API.
