Microsoft have determined the network connectivity issue is occurring with devices across the Microsoft Wide Area Network (WAN). This impacts connectivity between clients on the internet to Azure, as well as connectivity between services in datacentres, as well as ExpressRoute connections. The issue is causing impact in waves, peaking approximately every 30 minutes.

A recent WAN update as the likely underlying cause, and Microsoft have taken steps to roll back this update. The latest telemetry shows signs of recovery across multiple regions and services.
