With services offline for a week, the incident may reshape safety standards, insurance premiums, and infrastructure design, forcing enterprises to balance efficiency with resilience and regulatory compliance.
A catastrophic fire at South Korea’s National Information Resources Service data center has crippled 647 government systems for nearly a week, with 96 directly destroyed and 551 shut down preemptively, exposing critical vulnerabilities in disaster recovery execution and battery safety protocols that analysts say should prompt immediate CIO attention worldwide.
The September 26 incident, triggered when a lithium-ion battery exploded during routine UPS maintenance at the facility in Daejeon, has paralyzed essential government services, including banking, postal operations, identity verification, and emergency services.
As of Tuesday, only 85 services had been restored, with authorities projecting a four-week recovery timeline, Yonhap News agency reported.
In a related development, the same day, UK network operator Openreach issued an emergency directive giving communications providers 48 hours to remove all lithium batteries from BT exchanges “due to the significant risks of thermal runaway, fire and explosion,” according to ISPreview.
When safety measures backfire
The fire began during what was intended as a risk-reduction exercise — relocating UPS batteries from a fifth-floor server room to the basement to separate them from critical IT infrastructure.
The fire originated from a UPS battery disconnected for relocation. The explosion triggered thermal runaway, releasing extreme heat that complicated firefighting efforts. Authorities initially avoided using water to prevent data damage, instead relying on carbon dioxide suppression — a decision that contributed to the 22-hour firefighting effort, the Korean Herald reported. All 384 lithium-ion batteries were destroyed, the report added.
The batteries, manufactured by LG Energy Solution and installed in 2012-2013, had exceeded their 10-year lifespan despite passing safety inspections in June, the Korea Herald reported. Quoting industry experts, the report said that workers may have disconnected cables without properly shutting off power, causing voltage spikes in the DC system.
President Lee Jae Myung issued a public apology Sunday, calling the incident “foreseeable” and criticizing inadequate backup systems. On Tuesday, he ordered comprehensive infrastructure inspections across all government agencies.
The outage has disrupted mobile ID verification for banking and airports, postal services, transportation systems, and the government’s internal Onnara intranet, the report added.
The Lithium-ion risk calculation
The timing raises questions about an industry-wide technology shift. Lithium-ion batteries are projected to account for 38.5% of the data center battery market by 2025, up from 15% in 2020.
“As lithium-ion systems gain traction, the safety envelope must tighten,” said Tanvi Rai, senior analyst at Everest Group. “It’s essential to isolate battery modules away from server spaces, deploy early thermal and gas sensing, use suppression systems designed for lithium-ion failure modes, and adopt rigorous operational protocols.”
According to the Korean Herald report, there were 55 UPS-related fires in South Korea between 2018 and October 2022. The report noted that UPS systems often have simpler safety designs than large-scale energy storage systems, with batteries frequently housed near servers. At NIRS, batteries were positioned just 60 centimeters from servers.
Himanshu Mhatre, senior analyst at Everest Group, said fire suppression approaches need rethinking. “Clean-agent systems such as Novec 1230 or Inergen, paired with high-pressure water mist cooling, are far more effective than conventional sprinklers against lithium-ion fires,” he said. Facilities should incorporate blast relief panels and enhanced ventilation to reduce systemic failure risk, he added.
Mikhail Jaura, senior research analyst for cloud infrastructure at IDC Asia/Pacific, said high-profile incidents may temporarily slow adoption among risk-averse organizations. “However, I expect overall market momentum to continue, driven by the need for higher efficiency and density in AI-ready datacenters,” he said. “Vendors are increasingly offering integrated safety solutions for lithium-ion UPS systems, and regulatory scrutiny is rising.”
The disaster recovery execution gap
Beyond battery chemistry, the incident exposed what analysts describe as a critical vulnerability in disaster recovery architecture.
NIRS operates three geographically distributed sites housing approximately 1,600 government systems. However, over 647 systems — more than a third — were concentrated at the Daejeon facility. When fire struck, all 647 went offline simultaneously.
The Korea Herald, citing industry experts, reported the facility lacked “twin server” architecture enabling real-time failover. Quoting Interior Minister Yun Ho-jung, the report added that relocating 96 destroyed systems to cloud infrastructure in another location would take four weeks — double initial estimates.
“The recent outage reinforces that over-centralization invites systemic vulnerability,” said Rai. “Enterprises should recalibrate toward a hybrid topology, retaining scaled central facilities where appropriate, but pairing them with regionally distributed failover nodes, service segmentation, and built-in disaster recovery.”
Kasthuri Jagadeesan, research director at Everest Group, said enterprises should audit centralization risks by mapping interdependencies across UPS, cooling, and shared power zones. “The NIRS case illustrates that redundancy alone cannot protect against weak compartmentalization,” she said, noting that outages can cost millions per hour.
“Geographic redundancy is only effective if failover processes are tested and staff are trained to execute under pressure,” Jaura said. “CIOs must validate that DR plans are operational, not theoretical. This means regular, realistic testing, cross-functional engagement, and continuous improvement.”
IDC research shows that centralized facilities offer economies of scale but concentrate risk, while distributed and modular approaches enhance resilience and reduce single points of failure, according to Jaura. “Diversify datacenter locations to mitigate regional risks,” he advised. “Invest in modular and mobile data center solutions for flexibility and rapid recovery.”
Market implications
Rai said the incident may instigate “heightened due diligence and a more cautious pace of adoption,” but lithium-ion technology’s advantages remain compelling. “What is likely to change is that enterprises will demand stronger safety certifications and vendor accountability, and accelerate investment in disaster recovery planning, geographical redundancy, and resilience frameworks.”
Kalyani Devrukhkar, senior analyst at Everest Group, said both enterprises and regulators will be more demanding about safety standards. “Some organizations may look at alternatives like sodium-ion or advanced valve-regulated lead-acid, and insurers will almost certainly raise premiums where risk is seen as high,” she said, noting that NFPA 855 and newer International Fire Code editions now include stricter requirements for lithium-ion battery systems.
“Enterprises are increasing budgets for business continuity management, IT disaster recovery planning, and alternative site management,” Jaura said. For CIOs, Jaura recommended a business impact analysis-driven framework that balances efficiency with safety and compliance. “The decision is not binary — mitigation such as advanced monitoring, fire suppression, and modular design can allow continued use of lithium-ion batteries in lower-risk scenarios,” he said.
