Facing issue with us-east-1

I would suggest that you check AWS Service Health Dashboard first

Visit the AWS Service Health Dashboard https://health.console.aws.amazon.com/ to check for any reported issues or maintenance activities in the us-east-1 region

You can as well open a support case to AWS to get direct assistance from their support team. Provide them with detailed information about the issues we are experiencing, including timestamps and affected resources. They can offer insights and assist in diagnosing the root cause of the performance issues.
