Microsoft outage: MU professor weighs in on global service disruption

MILWAUKEE (CBS 58) -- Microsoft says its services are gradually returning to normal after a massive global outage disrupted schools, businesses and government agencies. The problems began Thursday, affecting services like Outlook, Teams and Copilot. 

Microsoft says there's no evidence of a cyberattack. Instead, the company says the outage was linked to a technical issue involving a network upgrade. The disruption is now raising bigger questions. 

Joining us is Dr. Michael Zimmer, a computer science professor at Marquette University and director of its Center for Data Ethics.
