Microsoft blackout sparks global chaos as servers crash

A worldwide outage has hit Microsoft Outlook and its wider cloud services hard. People in the United States and Australia were among the worst affected. But the rest of the world was also mightily affected.

According to Agence France-Presse, the disruption knocked tens of thousands of users offline.

Tracking website Downdetector recorded nearly 130,000 error reports on the U.S. East Coast alone.

Microsoft stated last night that the company had found the problem: “A process on the affected servers responsible for establishing secure connections becomes overwhelmed, causing the servers to stop processing requests.”

Ruling out a hack

Australia’s home affairs minister, Tony Burke, received direct assurances from the tech giant that this was not part of a larger cyberattack.

However, countless companies rely on Microsoft’s email service. Key organizations like Australia’s federal police and intelligence service lost access to their systems, AFP reported.

Microsoft blamed the crash on an elevated load straining its infrastructure. Beyond email, the failure dragged down tools like Teams, Planner, and SharePoint.

Rebuilding the connection

The company first started investigating reports from North and South America. It soon realized the trouble stretched much further.

Microsoft released a statement saying it had “confirmed that the issue may affect access to Microsoft 365 services for users in all regions.”

Engineers worked frantically behind the scenes to fix the servers. Just before midnight, the company shared a hopeful update on its website.

“We have begun putting some of the affected servers back into operation, and they have so far remained stable. We have also rerouted traffic and connections through alternative paths where possible, and we have observed limited recovery in some regions,” the company announced.

Relief on the way

Fixing a global cloud network takes time. Files and programs live online rather than on local computers, so every user needs a stable server connection.

The tech firm promised that things would slowly return to normal.

“As capacity is restored, users may experience gradual relief as their applications reconnect,” Microsoft added.

Here are the programs affected by the blackout:

• Exchange Online

  
  

• Microsoft Teams

  
  

• SharePoint Online

  
  

• Microsoft Copilot 365
