# South Korea National Emergency Medical Data System failures > Live situation record from CLSTR: https://clstr.news/situations/south-korea-national-emergency-medical-data-system-failures > Updated: 2026-09-30T01:12:43.000Z. Sources: 4. Developments: 2. The National Emergency Medical Data System (NEDIS) in South Korea has faced several technical failures between 2024 and August 2026. Data indicates four distinct system errors, with three occurring in February and March 2026. One major outage lasted over 32 hours due to the system’s storage partition reaching maximum capacity, which blocked hospitals from transmitting patient data. Subsequent errors in March involved redundant server failures lasting between approximately one and two and a half hours. While the National Medical Center reported that emergency room treatments were not interrupted and that capacity-related fixes have been implemented, Representative Heo Jong-sik has raised concerns regarding data integrity. He noted that transmission delays could impact the reliability of national medical statistics and has called for stability diagnoses, disaster recovery drills, and standardized reporting systems. ## Timeline ### 2026-09-30: National Emergency Medical Data System faces multiple technical failures South Korea's National Emergency Medical Data System (NEDIS) suffered three technical failures this year, including one outage lasting over 32 hours, raising concerns over national medical data reliability. 2 sources. https://clstr.news/cluster/national-emergency-medical-data-system-faces-multiple-technical-failures ### 2026-09-03: INEM emergency systems experience two-hour outage INEM's emergency coordination centers (CODU) experienced a two-hour IT system failure on Thursday, though contingency protocols ensured emergency calls and medical responses remained uninterrupted. 2 sources. https://clstr.news/cluster/inem-emergency-systems-experience-two-hour-outage --- Cite as: South Korea National Emergency Medical Data System failures.
