Latest Message<\/th>\nTitle: Admins may be unable to access the Deep Analysis functionality within the Microsoft Defender XDR portal<\/p>\n

User impact: Admins may have been unable to access the Deep Analysis function in the Microsoft Defender XDR portal.<\/p>\n

Final status: We determined that this issue was caused by a recent deployment that introduced a faulty error handling logic regression, which caused critical APIs to return 404 errors. We completed a reversion of this deployment and have since confirmed this remediated impact.<\/p>\n

Scope of impact: This event may have impacted some admins from being unable to access the Deep Analysis function in the Microsoft Defender XDR portal.<\/p>\n

Start time: Thursday, November 20, 2025, at 1:00 PM UTC<\/p>\n

End time: Friday, November 28, 2025, at 12:40 AM UTC<\/p>\n

Root cause: A recent deployment aimed at enhancing our services introduced a faulty error handling logic regression that caused critical APIs to return 404 errors, which resulted in impact.<\/p>\n

Next steps:
– We’re reviewing our deployment processes to better understand how we might detect and prevent similar service incidents from reoccurring.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
