One of the largest food store chains in Sweden had their entire card payment go down because someone forgot to handle leap years!


Wikipedia says they are "the second largest retail company in the Nordic countries[citation needed]". Pretty big company anyway and embarrassing for them. Would love to learn more about what the bug was, but I guess they will never say.

Is that intended as a correction? It’s a different claim, as far as I can tell, and the data I could find points to ICA in fact being the largest supermarket chain in Sweden by turnover.

No disagreement, just additional information.


Tbh I was just too lazy to find its place in the rankings. It sure is a big business anyway


This isn't even one of the weird years!

Is this why we can't have nice things?
