A major technical outage paralyzed 128 credit cooperatives in western Japan: ATMs, online banking and customer service at branches all stopped working at the same time. According to Bloomberg, the problem affected more than 3,400 branches.

Representatives of the cooperatives attributed the outage to equipment failure and warned that the problems would not be fixed by the end of the day.

For a country heavily reliant on cash transactions, ATMs going offline on Friday afternoon was about the worst possible scenario.
