Investigating issues in the Central US region

Impact Statement: Starting at approximately 21:56 UTC on 18 Jul 2024, a subset of customers may experience issues with multiple Azure services in the Central US region including failures with service management operations and connectivity or availability of services.Current Status: We are aware of this issue and have engaged multiple teams. We’ve determined the underlying cause. A backend cluster management workflow deployed a configuration change causing backend access to be blocked between a subset of Azure Storage clusters and compute resources in the Central US region. This resulted in the compute resources automatically restarting when connectivity was lost to virtual disks. Mitigation has been confirmed for all Azure Storage clusters, the majority of services are now recovered. A small subset of services is still experiencing residual impact. Impacted customers will be continuing to communicate throuhg Azure service health portal. The next update will be provided in 60 minutes, or as events warrant.https://learn.microsoft.com/azure/architecture/resiliency/recovery-loss-azure-region .
