A outage of Microsoft systems caused ripple effects and service disruptions globally – grounding flights, shutting down slot machines in Las Vegas and causing system problems at all types of businesses.

At the heart of the massive disruption is CrowdStrike, a cybersecurity firm that provides software to scores of companies worldwide. The company says the problem occurred when it deployed a faulty update to computers running Microsoft Windows, and that the issue behind the outage was not a security incident or cyberattack.

CrowdStrike has said a fix is on the way. Disarray continued hours after the problem was first detected, though by mid-morning Friday some businesses’ operations showed signs of normalcy.
