Datacenter Cooling Event - Southeast Asia

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 have proactively powered down four storage scale units to avoid potential damage to the hardware. All impacted storage scale units are in the same datacenter, within one of the region’s three Availability Zones (AZs). Beyond storage resources, 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).
