On September 26, 2025, South Korea experienced a critical event: a fire at the National Information Resources Service (NIRS, Daejeon) paralyzed much of the country’s public administration. Within hours, more than 600 digital services went offline.
Weeks later, the case is still a major topic—not only because of its impact on citizens, but also due to the fragility of the infrastructure and the huge lessons it leaves for the entire Data Center sector.
Timeline of a Digital Catastrophe
- Sept 26–27: A fire breaks out at the Daejeon NIRS, apparently caused by the explosion of a backup battery during maintenance. The fire is extinguished the following day, but the hall is rendered unusable. Cyber alert level is raised.
- Sept 28–30: A rushed migration of services begins toward the Daegu site. At this stage, less than 10% of systems were online.
- Oct 6–7: The government confirms that only 25% of services (163 out of 647) have been restored. Reports indicate 96 systems severely damaged and the potential loss of up to 858 TB of data.
- Oct 10: After two weeks, most government platforms remain down, with full recovery expected to take several more weeks.
Services Affected
The impact was nationwide. Among the most affected:
- Digital identity and mobile verification.
- Government email.
- Postal service payments and transfers.
- Passport issuance.
- Real estate transactions.
- Social aid platforms.
Millions of citizens saw everyday processes—once taken for granted—suddenly disrupted.
The Scale of the Loss
Although investigations are still ongoing, estimates point to hundreds of terabytes of permanently lost government data. This figure reveals not only the physical damage caused by the fire, but also the lack of a solid backup and recovery strategy.
How Could This Have Been Prevented?
The lessons apply to any Data Center, public or private:
Redundancia activa-activa: para que el fallo de un sitio no signifique el colapso total.
Backups inmutables y probados: no basta con almacenar; hay que restaurar en simulacros reales.
Seguridad en salas de baterías: aplicar normativas específicas para Li-ion (NFPA 855, IEC 62933).
Pruebas de caos y game days: entrenar la infraestructura para fallar de forma controlada.
Gobernanza del dato: clasificar la criticidad y definir RTO/RPO claros para cada servicio.
The Missing Piece: a DCiM
This is where DCiM (Data Center Infrastructure Management) comes in:
- Real-time visibility: identify risks before they become critical.
- Predictive alarms: anticipate failures in batteries or UPS.
- Automated response: switch loads and reorganize resources without waiting for human intervention.
- Data integrity: traceability and validation of backups to ensure no information is lost.
A DCIM cannot prevent a fire, but it can prevent a local incident from becoming a nationwide blackout.
Prevention Checklist for Data Centers
To prevent this case from happening again in another country or company, here is a practical list of key measures.

The NIRS fire is not just an isolated accident—it is a reminder that Data Center management requires an integral vision and resilience. South Korea, a global tech leader, saw how a physical failure translated into a national digital crisis.
Moral of the story: investing in redundancy, real backups, and DCIM is not optional; it is the only way to ensure that—even in the worst scenario—services never stop.
