We have identified root cause resulting in increased propagation times of DNS edits to the Route 53 DNS servers, and are working towards recovery. The Route 53 API is now accepting changes again, though these changes are still experiencing delays propagating as there is a significant backlog of changes to process. Queries to existing DNS records are not affected by this issue. This will also affect provisioning of new resources that rely on Route 53 for DNS, such as: EFS, PrivateLink, Amazon MQ, Amazon Managed Streaming for Apache Kafka, API Gateway, DocumentDB, FSx for Lustre, Certificate Manager, Transfer for SFTP, EKS, CloudFormation, Chime Voice Connector, Global Accelerator, RDS and SageMaker Ground Truth.
