    We are currently experiencing elevated provisioning times and limited impact to some clusters hosted in AWS US-EAST-1 due to an ongoing infrastructure incident affecting a single AWS Availability Zone (use1-az4). AWS has identified the issue as a thermal/power event impacting EC2 and EBS resources in that zone. Our team is actively monitoring the situation and AWS has shifted traffic away from the affected infrastructure. Other Availability Zones remain operational and unaffected. We will continue to provide updates as more information becomes available.
