```diff
+ Last update from AWS:  [02:01 AM PDT] We have identified a potential root cause for error rates for the DynamoDB APIs in the US-EAST-1 Region. Based on our investigation, the issue appears to be related to DNS resolution of the DynamoDB API endpoint in US-EAST-1. We are working on multiple parallel paths to accelerate recovery. This issue also affects other AWS Services in the US-EAST-1 Region. Global services or features that rely on US-EAST-1 endpoints such as IAM updates and DynamoDB Global tables may also be experiencing issues. During this time, customers may be unable to create or update Support Cases. We recommend customers continue to retry any failed requests. We will continue to provide updates as we have more information to share, or by 2:45 AM.
