 The impacts have been wide-ranging, from hospitals cancering surgeries to thousands of flights grounded. Keep in mind, this is not just an airline problem. This problem, this tech outage, goes around the world. It's affecting banks, hospitals, companies like FedEx and CBS. And it's all from one company, a cybersecurity firm called CrowdStrike. They did a software update that had an error in it, and the CEO of CrowdStrike says this was not a cyber attack.
