🔗 https://status.cloud.microsoft
Microsoft incident references: EX1550543 (Exchange Online) and MO1550821 (Microsoft 365)
*What Microsoft says caused it* (13 Nov, 17:57 UTC)
_"The incident was introduced by an issue during an earlier network capacity upgrade that surfaced following a recent network change. We have addressed the underlying issue and continue to restore service to remaining customers and regions."_
_"This was a technical issue not related to cyber or AI / agents."_
*How it unfolded, in Microsoft's words*
• 12 Nov, 19:18 UTC: _"the elevated load isn't driven by an overall increase in traffic, but by a large number of servers being unexpectedly unavailable, which is shifting load onto the remaining infrastructure."_
• 13 Nov, 01:06 UTC: _"a process on the affected servers responsible for establishing secure connections becomes overwhelmed, causing the servers to stop processing requests."_ Microsoft began _"reverting a recent network configuration change that correlates with the start of impact."_
• 13 Nov, 07:25 UTC: _"positive results for server stability after applying an upstream authentication/routing configuration component patch"_
• 13 Nov, 17:57 UTC: _"Given the scale of demand, we restored services gradually, validating stability at each stage."_
*Where things stand*
Microsoft reports _"broad recovery and stability across our services"_ but has not yet closed the incident. Delayed email is protected: Microsoft extended _"the email timeout window to 48 hours to help protect delayed messages."_
Microsoft said: _"We are deeply sorry for the disruption this incident has caused you and your business."_ It has not yet given more detail on the upgrade itself: _"We will provide a full post-incident report once our review is complete."_
Microsoft's next update is due at 20:00 UTC (22:00 South African time).
