It seems that good old human forgetfulness is just as likely to take out the UK's banking infrastructure as today's high-profile hacking attempts, thanks to Cydesdale and Yorkshire banks losing connectivity for a few days after their owner forgot to renew a critical domain name in time.
It wasn't actually a customer-facing domain that brought down Cydesdale and Yorkshire bank's online services for a short time, but an expired domain the technical system used to manage the systems and serve content. As an anonymous technician from the company told Computerworld: "Cbonline.co.uk is registered with Easyspace, along with several others, but the domain on their DNS servers, which is nabgroup.com, is managed directly by the NAB Group – that’s the domain name they didn't renew in time."
National Australia Group, which ironically owns the two local UK banks, claimed a "systems update" broke the service for its customers, although it might want to change that to a "complete balls up." [Computerworld]
