Update: Microsoft identified the problem as stemming from Azure, the company’s cloud computing platform.
The Azure status page said: "Starting at approximately 09:00 on 3rd Dec, 2015, customers began experiencing intermittent issues accessing Azure services that use, or have dependencies on Azure Active Directory.
"Engineering teams have identified an Azure Active Directory configuration error that is believed to be the root cause of the issue. The team is working on failing over the impacted service components to a different environment. Impact is largely centralized to the West Europe and North Europe regions. An update will be provided in 60 minutes, or as events warrant."
