Outage Details

Between 07:05 UTC and 09:45 UTC on 25 January 2023, customers may have experienced issues with networking connectivity, manifesting as network latency and/or timeouts when attempting to connect to Azure resources in Public Azure regions, as well as other Microsoft services including M365, PowerBI.We've determined the network connectivity issue was occurring with devices across the Microsoft Wide Area Network (WAN). This impacted connectivity between clients on the internet to Azure, as well as connectivity between services in datacenters, as well as ExpressRoute connections. Current Status:We have identified a recent change to WAN as the underlying cause, and have taken steps to roll back this change. Our telemetry shows consistent signs of recovery from 09:45 UTC onwards across multiple regions and services. Most customers should now see full recovery as WAN networking has recovered fully. We are working to monitor and ensure full recovery for services that were impacted.The next update will be in 30 minutes or as soon as we have further information.
