infomoney.com.br (Portuguese) —

Microsoft is working to fix a widespread outage affecting services like Outlook and Teams, but says there is no sign of a cyberattack. The disruption has impacted government and school users from the US to Australia. The company said initial fixes are not working as expected, though it observes partial recovery in some regions. Downdetector recorded tens of thousands of complaints, and third-party services like ChatGPT were also affected. The outage has been compared to similar 2025 disruptions at Cloudflare and Amazon Web Services, highlighting risks of relying on a single provider. Many services remained unstable into Friday morning.
