Latest Message<\/th>\nTitle: Users may be unable to access certain features in the Microsoft Defender XDR portal<\/p>\n

User impact: Users may have been unable to access certain features in the Defender XDR portal.<\/p>\n

More info: This issue impacted access to the Live Response, Isolation, and Device Onboarding status features in the Defender XDR portal. The tabs where these features would be located in the Defender XDR portal may have been missing.<\/p>\n

Final status: We’ve confirmed that the issue was remediated following the full saturation of the change to reverse the offending update, which took more time than initially expected.<\/p>\n

Scope of impact: Some users who attempted to access the Live Response, Isolation, and Device Onboarding status features from the Defender XDR portal may have been impacted.<\/p>\n

Start time: Tuesday, October 1, 2024, at 9:00 AM UTC<\/p>\n

End time: Thursday, October 3, 2024, at 8:00 PM UTC<\/p>\n

Root cause: Authentication requests weren’t being routed correctly due to a larger than expected size of the header data transmitted in the requests, which resulted in impact.<\/p>\n

Next steps
– We’re reviewing the routing process of authentication requests to better understand how they were in a position to become impacted by the larger than expected size of header data being transmitted in the requests. This will help us optimize our service to avoid similar issues in the future.
– We’re implementing additional service monitoring so we can more quickly identify and address similar issues in the future.<\/p>\n

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