  • Statement from Microsoft:
    • Current status: "We are aggressively pursuing all pathways to reduce impact. As a precaution, all  all deployments and configuration changes have been paused while we review recent changes for any correlation to this event. We've determined that 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. We're investigating what's causing these servers to become unavailable while we work to safely return them to service." 


Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services.
