Government Systems Stuck in Redundancy Quagmire Like Kakao

Government IT Systems Face Criticism After Fire at Daejeon Data Center

A recent fire at the Daejeon National Information Resources Management Service’s computer room has sparked significant criticism over the government’s reliance on inadequate cloud redundancy for data storage. This event highlights a recurring issue that was previously seen during the ‘Kakao outage’ in October 2022, now impacting public administration systems.

The affected computer room is part of the ‘G-Cloud Zone,’ an initiative by the National Information Resources Management Service to meet the IT needs of various administrative institutions. The disaster recovery (DR) system typically requires both server and cloud DR environments. However, reports indicate that while the server DR environment is in place, the cloud DR environment remains underdeveloped. This lack of comprehensive redundancy means that critical data is not being replicated across multiple locations, increasing vulnerability to disruptions.

In addition, the backup servers are housed in a single building, which poses a significant risk if another incident occurs. Although plans were in place to establish redundancy with the Gongju Center, progress has been hindered by budget constraints and other challenges. This delay in implementing a robust disaster recovery strategy has raised concerns about the resilience of the government’s IT infrastructure.

Similarities to the Kakao Outage Incident

This situation bears striking similarities to the fire at Kakao’s Pangyo data center in October 2022. At that time, the lack of proper data center redundancy led to widespread service disruptions. Following that incident, the government claimed that major national information systems, such as Gov24, the resident registration system, HomeTax, and the National Comprehensive Electronic Procurement System, perform real-time mutual backups between the Daejeon and Gwangju centers. It also stated that the disaster recovery system is designed to restore data from real-time backups within three hours.

Despite these claims, the current fire in Daejeon raises questions about the effectiveness of these measures. The fact that the same issues—insufficient redundancy and centralized backup systems—are reappearing suggests that there may be systemic gaps in how the government manages its digital infrastructure.

Common Cause: Issues with Uninterruptible Power Supply

The cause of the fire in Daejeon is also similar to the Kakao incident. Reports indicate that the fire originated from problems with the uninterruptible power supply (UPS), a critical component designed to provide continuous power during outages. The failure of this system can lead to severe consequences, especially in environments where data availability is paramount.

This incident underscores the importance of maintaining reliable and redundant power solutions in data centers. A single point of failure in the power supply can result in catastrophic data loss and operational downtime, particularly when backup systems are not adequately implemented.

Lessons Learned and Future Steps

The repeated occurrence of such incidents highlights the urgent need for improved redundancy strategies across all levels of government IT infrastructure. Key steps include:

• Implementing multi-location cloud DR environments to ensure data is stored in multiple secure locations.
• Diversifying backup systems by avoiding reliance on a single building or facility.
• Investing in robust UPS systems and regular maintenance to prevent power-related failures.
• Enhancing transparency and accountability in IT management to address delays and budgetary constraints.

As the government continues to rely more heavily on digital services, ensuring the resilience of its IT infrastructure will become increasingly critical. The lessons learned from past incidents must inform future policies to prevent similar disruptions and maintain public trust in essential services.
