Deleting replicas

Even though Lambda@Edge can only be managed from us-east-1 region, functions deployed as Lambda@Edge (bound to CloudFront distribution) are being replicated across all regions in AWS when only they are used in other location.

Unfortunately replicas can’t be deleted manually. This will cause automated resource deletion, triggered by CloudFormation to fail.

This will not break stack update process, as unused resources are deleted in UPDATE_COMPLETE_CLEANUP_IN_PROGRESS phase, but will leave the function in us-east-1 region deployed. You will have to wait until all replicas are purged (usually few hours) and manually delete.
