Microsoft has suffered a global outage. A tech expert explains what went wrong
This outage shows why we must urgently prepare for digital outages in a similar way we do for natural disasters.
Microsoft experienced a significant global outage, leaving many of its widely used tools, including Outlook, Teams, SharePoint, and others, offline. DownDetector tracked over 130,000 reports of issues accessing Outlook. The tech company stated it was working urgently to restore services. While Microsoft did not disclose the root cause, experts suggest it could be due to a failure in the health checks that determine if servers can handle traffic.
When such checks fail, healthy servers may be removed, overwhelming the remaining ones with too much work. This could explain why services were unavailable despite no increase in traffic or malicious activity. The incident highlights the importance of preparing for digital outages, much like we prepare for natural disasters. Companies should have backup plans and test them regularly, just as communities practice for bushfires.
