CrowdStrike caused Windows outage chaos for airports, banks, and more. Here's what happened


A massive IT outage is causing trouble for millions of people around the world. If you're affected, there is a workaround.

In the US, Delta, American, United, Spirit, Frontier, and Allegiant airlines were all affected by the outage, and while some have started to slowly begin operations again, most have not. In Africa, customers of two major banks were not able to make payments with their cards at grocery stores and gas stations or use ATMs. Mike Walters, President and co-founder of Action1, a vendor of patch management software, suggested this type of problem happens due to inadequate testing scenarios and that deploying the update in phases could have stopped the issue from being so far-reaching.
