Aer Lingus is entitled to rely on its suppliers. What happened here ultimately was the second line, which was to be the backup line, should typically have been running some volume of customers to ensure it was fit for purpose such that if the main system went down it could switch over. The irony of this is that it was limping along on a quarter of a tank long before the main system cable went down. When Kyndryl switched over, the airline suddenly found it had, dare I say it, a pipe that was itself broken. You could not make it up, in fairness.
