Microsoft responds to major worldwide outage admitting fix is ‘not working as expected’
Microsoft has seen its services around the world stall and become disrupted for users, and now it says it hasn’t found a fix just yet.
Outage-tracking site Downdetector reports it first detected problems just after 4:15PM GMT on Thursday, November 12.
There, Outlook’s reported issues reached nearly 140,000 around 6PM GMT, in 74 countries within one hour.
With email, calendars, and AI tools around the globe suddenly not working as they should, per the BBC, Microsoft has since pegged the issue to 'elevated load' across its infrastructure due to servers becoming 'unexpectedly unavailable' and pushing their traffic into other servers.
However, what the company thought might fix it hasn’t worked out, leaving many in the lurch.
Microsoft executive Charles Lamanna said that thankfully, the problem wasn’t caused by a cybersecurity incident; however, regaining services has been ‘difficult’.
He wrote on X: "We regret that today's outages caused disruptions for our customers, and we are working to address the issue."
Getting services back has proved difficult. Microsoft first said it was seeing 'positive results' from efforts to restart systems, but later said the fixes were not working 'as expected.”
Evidently, this disruption is having a varied impact on local, national, and global services.
Today might just be the day we all realize how many companies use Microsoft services, because it’s probably more than you’d think.
For example, OpenAI said it was investigating an issue that was blocking its connections to Microsoft's services, and another AI company, Anthropic, said it had identified an issue regarding Microsoft 365.
It has also had an alleged impact on the UK’s ambulance service, as the GMB union told the BBC the Microsoft outage has been ‘serious’.
Rachel Harrison, the union's national secretary, told the outlet: “Those who work in 111 and 999 services are unable to refer patient details in the normal way, which is creating a massive backlog and has the potential for chaos."
Clinical and operational systems in the NHS, however, appear to be working, per the chief executive of the NHS Alliance.
Ciarán Devane said the NHS is trying its best to work around it, noting: "NHS leaders and their teams are working hard to minimize disruption, maintain essential services and support staff and patients who may be affected.
"NHS organizations have workarounds in place when email is unavailable, so contingencies are in place to manage situations like this," he said.
In an update by Microsoft at 9:30AM, it said it is seeing ‘early signs of stabilization,’ but service capacity has ‘not yet returned to normal levels.’
"As part of this effort, we are extending the email timeout window to 48 hours to help protect delayed messages while service recovery continues," the statement states.
Microsoft said it is continuing to ‘treat this with urgency,’ and will share a full report after the incident is resolved so that users can see what caused the problem.
