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 Points - South Korea experienced its most severe digital infrastructure incident due to a fire at the National Information Resources Service data center, which lasted 22 hours and took down 647 critical systems, accounting for approximately 40% of the national digital service framework [2][4][7] - The incident highlighted significant vulnerabilities in the country's reliance on a single data center and raised questions about the safety of lithium batteries in data centers [11][15] Incident Details - The fire broke out on September 26 during a battery migration operation, with a lithium battery igniting and causing rapid spread of flames, leading to temperatures reaching 160 degrees Celsius [4][6] - A total of 384 lithium batteries were completely destroyed, and around 740 computing devices were damaged [4][10] - The firefighting efforts involved 73 firefighters and 70 fire trucks, with one reported injury [5] Contributing Factors - Aging batteries, operational errors during the migration, and inadequate spacing between batteries and critical servers were identified as potential causes of the fire [6][15] - The data center's design did not meet recommended safety standards, such as maintaining a minimum distance of 90 cm between batteries and servers [6][15] System Impact - The fire led to the shutdown of 647 systems, with only 62 systems restored by the following Monday, indicating a recovery rate of less than 10% [10] - The incident caused widespread disruption to essential services, including digital identity systems, banking operations, and emergency services [7][10] Industry Implications - The event prompted a reevaluation of the safety protocols surrounding lithium batteries in data centers, as their market share in data center battery systems has increased from 15% in 2020 to an estimated 38.5% [15] - The incident is expected to lead to stricter operational guidelines and safety measures in the industry to prevent similar occurrences in the future [15]
