Is AWS SSM (or other services) down for anyone else?

Yep. I have seen these errors

botocore.errorfactory.InternalServerError: An error occurred (InternalServerError) when calling the GetParameter operation (reached max retries: 4): Server busy. Please try again.

botocore.errorfactory.InternalServerError: An error occurred (InternalServerError) when calling the GetParameter operation (reached max retries: 4): No Content-Type received. Service returned the HTTP status code: 500

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.

Amazon Web Services Service Status 18:46

Informational message: Increased API Error Rates and Latency We are investigating increased API error rates and latency in the US-EAST-1 Region. This will impact customers ability to make calls to parameter store.

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.

AWS saying it will be an hour until resolution.

Same here, seems to be recovering ...
