Internet-based bank Kakao Bank experienced two connection outages due to internal system configuration changes, causing inconvenience to many users. The first outage began around 3:29 PM on March 17, lasting approximately 26 minutes.

Kakao Bank initially attributed the connection failure to an update issue, restoring service after 26 minutes through rollback measures, but the actual cause took two hours to identify. It was only after 5:30 PM that the root problem was confirmed to be a configuration change in the application performance monitoring system, which caused the overload. During this recovery process, an additional 8-minute connection failure occurred.

Kakao Bank stated that although there was no direct financial loss to customers, they received a total of 184 customer complaints. The main issues included failures in new stock subscriptions. Kakao Bank added that they are studying compensation plans for affected customers.

Legislator Lee Ryang-su pointed out that this incident could cause serious concern among Kakao Bank’s 26 million users. He urged financial authorities to take this opportunity to thoroughly examine Kakao Bank’s systems and organization.

Such technical failures can undermine consumer trust. Financial institutions like Kakao Bank need to strengthen internal system management and fault response mechanisms. Establishing preventive measures is crucial to avoid similar incidents in the future.
