The Financial Supervisory Service (FSS) is looking into whether Kakao's financial affiliates took timely countermeasures after a fire broke out at a data center on Saturday.

According to the financial authority, it demanded KakaoBank, Kakao Pay and Kakaopay Securities submit their real-time response actions for the weekend.

The inspection came in reaction to growing public complaints over hours-long service disruptions of the financial services run by the mobile platform operator.
