Lloyds Banking Group serves about 30 million customers and is the largest retail banking group in the UK. TSB has about five million UK customers and is in the process of being split from Lloyds Banking Group.

TechUK, a trade body for a number of technology companies, said: "It is now widely acknowledged that the technology infrastructure across many financial institutions is exceptionally complex, to the point where it no longer serves many banks, it hinders them.

I've no idea about TBS/Lloyds internal systems, but if a server running a network controller whose job is to route traffic to their different mainframes at different computer centres breaks that would explain why some ATMs were ok, some weren't.

Banks computer systems have been having outages for years. These days its more high profile due to social media like twitter. A lot of people rely on a card more than good old cash. No backup.
