The recent Microsoft outage in July 2024 had widespread impacts, disrupting various services and businesses globally. The outage primarily affected Microsoft 365 services, including Microsoft Teams, Outlook, OneDrive for Business, Exchange Online, and SharePoint, causing significant issues for users in Europe, Asia, and beyond.
The root cause of the outage was identified as a wide-area networking (WAN) routing change. A command given to a WAN router caused it to send messages to all other routers in the network, which led to them recomputing their adjacency and forwarding tables. During this re-computation process, the routers failed to forward packets correctly, resulting in connectivity issues.
Additionally, the outage affected services relying on Bing's API, such as DuckDuckGo and ChatGPT. Users encountered error messages and were unable to load search results on these platforms. The disruption in Bing's API led to a ripple effect, impacting all dependent services.
Microsoft has acknowledged the issue and is working to prevent similar incidents in the future by blocking highly impactful commands and ensuring safer execution of commands on its devices. The company has been providing updates through their service health platform and Microsoft 365 Status account.
