A Microsoft Azure outage on July 30 was triggered by a distributed denial of service (DDoS) cyberattack, the tech giant has confirmed. This incident disrupted several Microsoft services, including Microsoft 365 products such as Office and Outlook, as well as Azure, affecting users worldwide.
The outage, which lasted nearly 10 hours, began at approximately 11:45am UTC and was resolved by 19:43pm, according to Microsoft’s Azure status history page. The company stated that a “subset of customers may have experienced issues connecting to a subset of Microsoft services globally.” This disruption impacted various services, including Azure App Services, Application Insights, Azure IoT Central, Azure Log Search Alerts, Azure Policy, the Azure portal itself, and a subset of Microsoft 365 and Microsoft Purview services.
The timing of this cyberattack is significant, coming less than two weeks after a flawed update from CrowdStrike caused widespread crashes on Microsoft Windows machines.
Microsoft’s prompt response and confirmation of the cyberattack highlight the growing challenges in securing cloud services and the critical infrastructure they support.
