Yep. I have seen these errors

Yes, also in us-east-1 and we currently have an event showing for it in our personal health dashboard (but doesn't seem to be acknowledged on the health dashboard if logged out). It's preventing us from deploying CloudFormation stacks as well right now.

Getting CloudFront internal errors preventing deployment...

`An error occurred (ServiceUnavailable) when calling the CreateInvalidation operation (reached max retries: 2): CloudFront encountered an internal error. Please try again.`

Us too - ssm is returning `software.amazon.awssdk.services.ssm.model.InternalServerErrorException: Server busy. Please try again. `

I can't deploy on CloudFormation to us-east-1 right now, getting various errors when creating changesets with AWS CDK.

Working for me now again.

AWS saying it will be an hour until resolution.

They just pulled that back. Resolution time is now unknown.

Same here, seems to be recovering ...
