An outage on Microsoft’s Azure cloud services Wednesday morning disrupted operations for customers worldwide including Alaska Airlines, Xbox users and 365 subscribers.
The incident strikes just ahead of Microsoft’s quarterly earnings call today and follows last week’s outage at Amazon Web Services and a failure of Alaska Airlines’ own data center technology.
The latest outage struck at 9 a.m. Pacific Standard Time, according to Microsoft, when the system “began experiencing Azure Front Door (AFD) issues resulting in a loss of availability of some services. We suspect that an inadvertent configuration change as the trigger event for this issue.
“We are taking several concurrent actions: Firstly, where we are blocking all changes to the AFD services, this includes customer configuration changes as well. At the same time, we are rolling back our AFD configuration to our last known good state,” the company stated. “As we rollback we want to ensure that the problematic configuration doesn’t re-initiate upon recovery.”
Alaska Airlines posted on X at 10:33 a.m., explaining that the Azure outage was disrupting systems including their website function. Passengers flying on Alaska and Hawaiian airlines who were unable to check-in online were directed to airline agents to receive their boarding passes.
“We apologize for the inconvenience and appreciate your patience as we navigate this issue,” the post said.
Microsoft did not indicate when the issue would be resolved.
“We do not have an ETA for when the rollback will be completed, but we will update this communication within 30 minutes or when we have an update,” the company posted at 10:51 a.m.
