Hard Questions for Microsoft as Its Outage Drags Into a Second Day and Restored Servers Fail Again

More than a day after Outlook first went dark, Microsoft still could not say what broke or when it would be fully fixed. The global outage that began Thursday afternoon stretched into Friday, and servers the company had brought back overnight failed again once traffic returned, Euronews reported ^[2]. By Friday morning Microsoft was reporting only marginal success ^[2].

That leaves governments, hospitals, courts and millions of workers with hard questions about how much of modern life now runs through a single company's servers.

What We Know

The trouble began at about 16:00 GMT on Thursday, 11 a.m. Eastern time, when users reported they could not reach Outlook, and within roughly an hour Downdetector had logged reports from 74 countries and territories, Al Jazeera reported ^[1]. Outlook was hit hardest, with web, app and mobile access failing and many messages arriving late, while Teams and Copilot were also disrupted ^[1]. Euronews reported that Microsoft's incident notice later grew to include SharePoint Online and its Defender XDR security service, and that Planner and To Do were also reported down ^[2].

The numbers are large. CBS News reported that more than 130,000 users reported Outlook problems at the peak on Thursday ^[3], and Euronews put the figure at nearly 140,000 reports for Outlook alone, noting that Downdetector measures scale, not a headcount ^[2]. Microsoft says more than 430 million people use its 365 apps ^[2].

In its Friday morning update, Microsoft said recovery actions were progressing in phases but that service health remained variable and capacity had not yet fully returned to normal, CBS News reported ^[3]. The company said it was taking a measured approach to repair the affected infrastructure and would treat the incident with urgency until it was resolved ^[3].

Who Was Hit

The damage reached well beyond office email. Singapore's Government Technology Agency said government emails were down, the Supreme Court of the Philippines said some operations were affected, and Japan's deputy chief cabinet secretary said the outage touched government IT systems, CBS News reported ^[3]. Australia's intelligence agency and federal police were affected, Al Jazeera reported ^[1].

Air India said its flights were not affected but it temporarily rerouted email, and IndiGo said its email support was disrupted, according to CBS News ^[3]. OpenAI and Anthropic reported problems with tools that connect their services to Microsoft 365, and electric truck maker Workhorse postponed its quarterly earnings call to Monday ^[2][3]. Several British family doctors' offices told patients to phone instead, Euronews reported ^[2]. A New Zealand technology executive told Euronews that many companies had simply lost a business day ^[2].

What Caused It

Microsoft has not published a root cause ^[1]. The company first blamed an elevated load across multiple regions, then said the load was not caused by more users, and that a number of servers had become unexpectedly unavailable, Al Jazeera reported ^[1]. Late Thursday it said its fixes were not taking effect as expected, and on Friday it was rolling back a network change without saying whether that change caused the problem ^[1].

The company says this was not an attack. Charles Lamanna, a Microsoft executive vice president, wrote late Thursday that there is "no indication this is the result of malicious or cyber activity," Al Jazeera reported ^[1]. Australia's home affairs minister, Tony Burke, said Microsoft had likened the event to the July 2024 CrowdStrike failure, when a faulty update grounded flights and disrupted banks and hospitals, CBS News reported ^[3].

Is Your Data at Risk?

Nothing Microsoft has said suggests customer data was exposed or lost, Euronews reported ^[2]. The bigger risks are indirect: weaker security monitoring while Defender XDR is disrupted, scammers using the confusion to send fake "fix your account" emails, and messages that arrive late or not at all ^[2].

There is not much individual users can do, because the fault is on Microsoft's servers, Al Jazeera noted ^[1]. Euronews suggested that desktop Outlook users try the Work Offline setting to read and draft messages already downloaded, check Microsoft's @MSFT365Status account on X and its status page, and use another tool such as Slack or Google Chat for urgent team messages ^[4]. Be wary of any email or call claiming to be Microsoft support.

The Hard Questions

This is not the first time. In January, Microsoft 365 went down across North America for almost 10 hours, and in August a faulty code update disrupted Outlook for days, according to Al Jazeera and Euronews ^[1][2]. Three major outages in one year raise fair questions for the company's leaders and for the governments that buy from it.

How many agencies that serve the public, from courts to police, have a backup if their only email system fails? Why did servers restored overnight fail again on Friday? And when will Microsoft give customers a full, public account of what happened? The company has promised continued updates but has not yet published a full review, Euronews reported ^[2].

For a free country, resilience matters as much as convenience. When so much of government, health care and commerce rides on one provider, an outage is not just an inconvenience. It is a test of whether anyone planned for the day the system goes quiet.

What Comes Next

Microsoft has given no timeline for full recovery and says service may come back gradually as apps reconnect, Al Jazeera reported ^[1]. CTV News, citing the Associated Press, reported that the company is still investigating the cause ^[5]. Watch for Microsoft's post-incident report, and for questions from lawmakers and regulators about what went wrong.
