Just a day after Microsoft announced its new Entra cloud identity services portfolio, one of Entra's core products suffered wobbly performance for more than 12 hours.
Microsoft warned that users of its identity service Azure Active Directory (AD), as well as several downstream Azure services, could have received "missed or misfired alerts". That's potentially a headache for customers who rely on Azure AD for controlling employee access to Office 365 and other apps. Customers might have also had problems accessing Azure Portal, MSGraph, Log Analytics, PowerShell, and Application Insights.
While this wasn't an outage, there was an extended period of "significant delays" in logging data from Azure AD and other services, which affected US Azure customers late on May 31 and Europe customers during the morning of June 1.
"Between 21:35 UTC on 31 May and 09:54 UTC on 01 Jun 2022, customers may have experienced significant delays in availability of logging data for resources such as sign-in and audit logs for Azure Active Directory and other Azure Services, accessing tools such as Azure Portal, MSGraph, Log Analytics, PowerShell, and/or Application Insights. This impact may have also resulted in missed or misfired alerts," Microsoft said.
After rolling out the fix, Microsoft removed the issue from the live Azure status page, which previously indicated the logging issue was affecting Azure AD globally.
While attempting to resolve the issue, Microsoft reported that services relying on Azure Resource Management were experiencing operation failures, too.
"During this time, Azure Resource Manager dependent services may have also experienced CRUD (create, read, update and delete) operation failures, with some requests that experienced failures while communicating with other Azure services," Microsoft said.
Given the length of the latest disruption to Azure AD, Microsoft said it will continue to investigate what went wrong to establish a "full root cause" and figure out how to prevent a future disruption.
