 From ABC News, I'm Michelle Franzen. This is a special report, Global IT Outage, a worldwide tech outage affecting Microsoft's cloud services and 365 apps, creating a ripple effect of troubles for companies, including airlines, with flights grounded temporarily today. Security agency CrowdStrike says it was a software issue not related to a cyber attack. A patch has been created to update the software, but the outage is triggering problems for retailers, transportation, and emergency operations.
