From PC World: On Tuesday July 30, users worldwide experienced disruptions with Microsoft services connected to the company’s Azure cloud platform.
According to initial reports, the outage mainly involved Microsoft 365 products, but eventually problems also surfaced with the Admin Center, Intune, Entra, and Power Platform services.
Since then, details have slowly come to light about the extent and cause of the disruption. It was apparently a DDoS attack on the company, according to Microsoft’s mitigation statement.
Users of Microsoft 365 services reported issues with access and degraded performance, some completely unable to use the services in question. The disruption lasted about eight hours and was resolved towards the afternoon with a temporary workaround.
We now know that there was an attack on Microsoft’s Azure cloud platform that attempted to overload the system.
Microsoft’s security measures successfully withstood the attack, but an error in the configuration caused the company’s own system to overload access to Azure. As a result, Azure services were unavailable or only accessible to a limited extent.
