  "summary": "Microsoft 365 services, including Outlook, Teams, Exchange Online, SharePoint Online, Copilot 365, and Microsoft Defender XDR, have been disrupted. XDA Developers reports that tens of thousands of outage reports have been made on DownDetector, noting that services such as OneDrive and Azure are also down. Additionally, reports indicate that some Google services, Steam, and Amazon Web Services are currently unavailable.\n\nMicrosoft stated that failed server health checks disrupted services and that it is investigating the cause. According to XDA Developers, the company determined that an elevated load is not driven by an increase in traffic, but by a large number of servers becoming unexpectedly unavailable, which shifts load onto the remaining infrastructure. As a precaution, Microsoft has paused all deployments and configuration changes while reviewing recent changes for any correlation to the event. SecurityWeek reports that Microsoft has disclosed no evidence of a cyberattack.",
