The underlying problem behind today's massive IT outage | DW News

A technical outage is disrupting companies worldwide - from airlines to broadcasters and banks. The US initially grounded all of its flights worldwide, as delays hit airports including Berlin and Amsterdam's Schipol. In the UK, the London stock exchange was temporarily affected and two hospitals in Germany had to cancel non-emergency operations. The problem is being linked to the cyber security firm Crowdstrike and the Microsoft Windows operation system.
