Microsoft reported a "networking configuration issue" on Wednesday morning which resulted in an outage of a number of the company's products including Microsoft Teams and Outlook. The biggest hit was Microsoft's Cloud service Azure, which made up 30 percent of the cloud computing market in 2022, reports Reuters

The main cause of the outage was a network connectivity issue, disrupting the connection between Azure and those on the internet. Many businesses use the software for their own products and services, writes BBC News. Companies and people also had issues joining calls or accessing and sending messages as well without Outlook and Teams. 

Microsoft pushed back a network change that the company determined was causing the issue and used "additional infrastructure to expedite the recovery process." These types of routine upgrades and maintenance leave systems susceptible to outages, even if only a small error occurs. In turn, it can lead to ripple effects like how Azure's outage led to the failure of a number of systems.
