一块电池，烧瘫韩国：数据中心失火 22 小时，647 套系统因缺失“双活”集体宕机

Core Insights - South Korea experienced its most severe digital infrastructure incident due to a fire at the National Information Resources Service data center, which resulted in 647 critical systems going offline, accounting for approximately 40% of the national digital service framework [1][9]. Incident Details - The fire broke out on September 26 during a battery transfer operation involving lithium batteries, which had been identified as a risk prior to the incident. The fire was ignited by a spark from one of the batteries, leading to a rapid escalation of the blaze [2][7]. - The fire reached temperatures of 160 degrees Celsius, causing the temperature and humidity control systems to fail, prompting the management to shut down all remaining equipment to prevent further damage [2][9]. - The fire was extinguished after 22 hours, resulting in the complete destruction of 384 lithium batteries and damage to 740 computing devices [3][4]. Response and Recovery - Approximately 73 firefighters and 70 fire trucks were involved in the rescue efforts, with one reported injury [4]. - As of the following Monday, only 62 out of the 647 systems had been restored, indicating a recovery rate of less than 10% [13]. Infrastructure Critique - The incident highlighted significant flaws in the infrastructure, including the aging of the lithium batteries, which were installed in 2014 and had surpassed their warranty period. Recommendations for replacement had been made but were not acted upon [7][15]. - Criticism was directed at the layout of the data center, where the distance between the batteries and critical servers was less than the recommended 90 centimeters, increasing the risk of fire spread [7]. Systemic Impact - The fire led to widespread service disruptions across South Korea, affecting critical systems such as mobile identification, banking services, and emergency response systems [9][10]. - The incident prompted the activation of the highest emergency response level for an IT disaster in South Korea, marking a significant escalation in the response to such incidents [10]. Industry Implications - The fire has raised concerns about the safety of lithium batteries in data centers, with experts calling for stricter safety measures, including better isolation of battery modules and improved fire detection and suppression systems [19]. - The market share of lithium batteries in data center applications has increased significantly, from 15% in 2020 to an estimated 38.5% currently, indicating a growing reliance on this technology despite the associated risks [19].
