A glitch in the post office financial network disrupted financial services nationwide before some were restored.
According to Korea Post on the 14th, starting around 3:14 p.m. that day, a network outage caused disruptions to deposits and insurance counter services, automated teller machines (ATM), and internet and mobile financial services.
Around 5:20 p.m., counter systems and ATM transactions were restored, but internet and mobile financial services were still not back to normal.
Korea Post said it is investigating the cause of the system failure and noted that it was not due to cyberattacks such as hacking.
