A major British Airways crash has highlighted the importance for businesses of testing backup systems and disaster recovery procedures to ensure that they work as planned.
The airline experienced what CEO Alex Cruz described as "a major IT systems failure" that, he said, affected all check-in and operational systems.
The failure on Saturday, May 27, resulted in the delay or cancellation of hundreds of flights, leaving thousands of passengers stranded at London's Heathrow Airport on a holiday weekend. Things were still not back to normal two days later.
Cruz described the cause of the failure as "a power supply issue," without going into detail.
