Toss Bank will strengthen key data center infrastructure to provide more robust and stable financial services.

Toss Bank said on Feb. 6 it will conduct a systems inspection from 1 a.m. to 8 a.m. on Feb. 8 to advance its data center. The inspection is the first large-scale work since its launch that involves a service halt of more than 1 hour.

The work focuses on upgrading server infrastructure to enhance financial stability and service processing capacity. It will also improve its ability to respond more efficiently to rapidly rising traffic and enable stable operations even in unexpected IT incidents.

Toss Bank has operated an "fully redundant" (Active-Active) data center system. The typical financial industry model of a "primary center-disaster recovery center" (Active-Standby) switches to a backup center when the primary center fails, making service interruptions unavoidable during the process.

Toss Bank operates 2 data centers at the same time to handle traffic. Even if one site shuts down in emergencies such as natural disasters or fires, the other center immediately takes over services, allowing operations to continue without interruption.

During the seven-hour inspection, access to the mobile banking app and all financial services, including transfers, will be temporarily suspended, and on- and offline payments using check cards will also be restricted.

A Toss Bank official said, "This data center upgrade is essential work so our 14,000,000 customers can use more stable financial services," adding, "We are sorry for the inconvenience during the inspection time, and we will finish it quickly and safely to improve service quality."
