Faulty software update causes global tech outage

A global technology outage grounded flights, knocked banks offline and media outlets off air after a faulty software update disrupted companies and services around the world and highlighted their dependence on just a handful of providers. Cybersecurity firm CrowdStrike said the trouble with the update it issued that was affecting computers running Microsoft Windows was not a security incident or cyberattack. It said a fix was on the way.
