Recovering

We are now seeing broad recovery of services. Microsoft has now addressed the underlying issue and are restoring services gradually. Mail flow may still be impacted as delivery services continue to catch up after the server outages. We are seeing more sustained mail flow and successfully delivery of some inbound and outbound emails

We do not have an ETA for full recovery yet.

We're starting to see some stability come back to Microsoft products. Microsoft is rolling out patches systemically to focus on infrastructure within regions currently within or entering peak business hours.

Microsoft update Nov 13 12:58 pm AEDT (1:58 AEST)

We’ve monitored the status of the changes applied to improve serviceability and confirmed that change is not taking as expected. We’re identifying alternate workstreams that can be applied to increase capacity in the face of sustained traffic management imbalances.


This update indicates that the outage is still ongoing as attempted remediation has not been successful so far. There is no ETA on resolution at this time

We’re seeing positive results with our efforts to restart affected infrastructure. We’re actively monitoring the performance of these to verify stability which will support improved availability. Remediation actions will be expanded as we confirm stability with the changes applied.

Recent updates indicate that Microsoft is working on a solution and has narrowed down possible causes, which they'll test on a subset of servers before attempting to use it more widely. They are undoing a recent network update that was rolled out at the same time the incident occurred. There is still no estimated time frame for resolution

Microsoft update Nov 13 10:00am AEST (11:00am AEDT)

While the servers we've returned to service initially remain healthy, we've observed that they can become unresponsive again once they begin receiving traffic.

Microsoft update Nov 13 8:58am AEST (9:58am AEDT)

We've begun returning a portion of the affected servers to service, and they're remaining stable so far. We’ve also shifted traffic and connections to alternative pathways wherever possible and have observed limited recovery in some regions.

As capacity is restored, users may experience a gradual recovery as their clients reconnect to the service.

Microsoft Update Nov 13 2026, 8:03am AEST (9:03am AEDT)

We’re continuing to pursue all available pathways to restore service, as our actions taken thus far have not provided the anticipated relief. Our investigation has found that a core process on the affected servers is becoming overwhelmed, which causes the servers to stop responding and contributes to the capacity loss.
