Outage Details
Issue Summary: Starting around 20:19 UTC on 7 February 2023, a utility power surge in the Southeast Asia region tripped all of the chiller units for one datacenter offline. While working to restore the chiller units, temperatures in the datacenter increased so we had proactively powered down compute, storage and networking resources to avoid damage to hardware. All impacted infrastructure is in the same single datacenter, within one of the region’s three Availability Zones (AZs). We are continuing to work through our structured power-up process, initially targeting storage resources, followed by compute resources. We are actively monitoring as we work through this extended process, and storage restoration is progressing well. Downstream services that have been identified as impacted include Azure App Services, Azure Backup, Azure Cosmos DB, Azure Database for MySQL & flexible server, Azure Database for PostgreSQL & flexible server, Azure Log Analytics, Azure Red Hat OpenShift, Azure Search, Azure SQL Database, and Azure Virtual Machines (VMs).
