Flyers Grounded By Tech Glitch

Why did British Airways passengers suffer cancelled flights and days of travel disruption because of a fault at a data centre? We ask airline IT expert Bert Craven of consultants T2RL why large companies are still vulnerable to computing failures. Plus, everyone knows about harassment and abuse on social media. But is the problem even worse in online games? We hear the experience of one young gamer and the view of Jo Twist from Ukie, which represents the UK games industry. And why is the hacking world unhappy with the chaos brought about by the WannaCry ransomware attack? We’ll find out from cybersecurity researcher Andrei Barysevich of the firm Recorded Future. Presented by Rory Cellan-Jones, with BBC tech reporter Zoe Kleinman, and special guest Mariéme Jamme, entrepreneur and new board member of the World Wide Web Foundation.
