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: Following our extended period of service monitoring and confirmation from additional affected users, we’ve confirmed that impact has been remediated. <\/p>\n

Scope of impact: Some users attempting 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: Tuesday, October 8, 2024, at 2:00 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, resulting in impact.<\/p>\n

Next steps:
– We’re further analyzing the routing of our authentication requests for larger header data levels so we can help prevent similar issues from producing impact in the future. <\/p>\n

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