A significant global outage affecting Microsoft services, particularly Microsoft 365, has caused widespread disruptions across various sectors, including airlines, banks, and health systems. The outage was attributed to a glitch in CrowdStrike's "Falcon Sensor" software, which impacted Windows systems, leading to thousands of flight cancellations and operational chaos in multiple industries. Microsoft has reported that the underlying cause of the outage has been fixed, but residual effects continue to impact some users as the company works on full recovery.
