Multiple Services - Applying mitigation with some recovery

CUSTOMER IMPACT: There are currently two identified impact workstreams:1) Customers with resources in South Central US may experience difficulties connecting to resources hosted in this region. A complete list of impacted services can be found below.2) Customers using non-regional services, such as Azure Active Directory, may experience intermittent authentication failures in any region.PRELIMINARY ROOT CAUSE:1) A severe weather event, including lightning strikes, occurred near one of the South Central US datacenters. This resulted in a power voltage increase that impacted cooling systems. Automated datacenter procedures to ensure data and hardware integrity went into effect and critical hardware entered a structured power down process.2) As a result, non-regional services, such as Azure Active Directory, encountered an operational threshold for processing requests through the South Central US datacenter. Initial attempts to fail over into other datacenters resulted in temporary traffic congestion for those regions.ENGINEERING STATUS: Engineers continue to implement the necessary mitigation steps. They have outlined a tentative mitigation workflow:1) Restore power to the South Central US datacenter (COMPLETED)2) Recover software load balancers for Azure Storage scale units in South Central US (COMPLETED)3) Recover impacted Azure Storage scale units in South Central US (In Progress)4) Recover the remaining Storage-dependent services in South Central US (In Progress)This mitigation workflow is tentative and subject to change as events develop.NEXT UPDATE: The next update will be provided by 00:00 UTC 05 Sep 2018 or as events warrant.

Azure Service Management Failures - Resolved

SUMMARY OF IMPACT: Between 22:15 on 26 Jun 2018 and 06:20 UTC on 27 Jun 2018, a subset of customers may have experienced timeouts or failures when attempting to perform service management operations on their API Management, App Service, Microsoft Stream, Media Services, Azure SQL Database, Azure Search, Azure Active Directory B2C, Azure IoT hubs, Azure Batch, Event Hubs and Service Bus services in Azure. In addition, some customers may have experienced connection failures to the Azure Portal. Some services with a reliance on triggers from service management calls may have seen failures for running instances.PRELIMINARY ROOT CAUSE: Engineers identified a service management API code configuration that impacted background services. This was causing service management requests to fail for a subset of customers.MITIGATION: Engineers performed a rollback of the recent deployment task to mitigate the issue.NEXT STEPS: Engineers will continue to investigate to establish the full root cause and prevent future occurrences.
