The Microsoft Azure Outage Shows the Harsh Reality of Cloud Failures
"Microsoft's Azure cloud platform, its widely used 365 services, Xbox, and Minecraft started suffering outages at roughly noon Eastern time on Wednesday, the result of what Microsoft said was "an inadvertent configuration change." The incident-which marks the second major cloud provider outage in less than two weeks-highlights the instability of an internet built largely on infrastructure run by a few tech giants."
"Microsoft's problems specifically originated from Azure's Front Door content delivery network and emerged just hours before Microsoft's scheduled earnings announcement. The company website, including its investor relations page, was still down on Wednesday afternoon, and the Azure status page where Microsoft provides updates was having intermittent issues as well. Microsoft described in status updates on Wednesday that it went through a process of sequentially rolling back recent versions of its environment until it could pinpoint the "last known good" configuration."
An inadvertent configuration change in Azure Front Door triggered outages across Microsoft's Azure cloud, 365 services, Xbox, and Minecraft around noon Eastern. The outage occurred just hours before Microsoft's scheduled earnings announcement and left the company website, including the investor relations page, and the Azure status page intermittently unavailable. Microsoft sequentially rolled back recent environment versions to identify the last known good configuration and at 3:01 pm ET pushed a stable configuration, beginning node recovery and rerouting traffic through healthy nodes. A Microsoft spokesperson advised customers to monitor Service Health Alerts. The outage followed a major Amazon Web Services outage nine days earlier, underscoring concentration risks among hyperscalers.
