Businesses including banks, airlines, train companies, telecommunications companies, TV and radio broadcasters, and supermarkets have been affected by a mass global IT outage.
Major US airlines including American Airlines, Delta Airlines and United Airlines have been grounded, while airports in Germany, Amsterdam and Spain are also reporting issues.
It is believed the outage was related to an issue at global cybersecurity firm CrowdStrike and Microsoft – although it is unknown if it is the same issue affecting airports and train services across the globe.
According to an alert sent by CrowdStrike to its clients, the company’s falcon sensor software caused Microsoft Windows to crash and display a blue screen, which has begun to be referred to as the “blue screen of death”.
