 deployed an update. That update, once deployed, caused a number of windows-based workstations to go offline or crash, critically fail. And in order to do a restoration, it requires someone to manually touch each one of those workstations. Early this morning, the FAA issued a ground stop for some major airlines, including Delta, American, and United. Those are slowly coming back online. CrowdStrike once again reiterating the outage is not a cyber attack.
