Maybe this illustrates part of the problem. The first reaction seems to be who to blame and can we claim compensation. Not invalid questions, but in my experience, which includes ATM systems, the problems often arise from failing properly to define what the system must do and to manage/handle errors and unexpected data in a robust way. Time will tell what went wrong yesterday, but I would be surprised if it wasn't something that could have been predicted (but maybe wasn't handled in a managed way).
