Daejeon: Public administration services were expected to see disruptions for a fifth day Tuesday as the government races to restore systems damaged by last week’s fire at the state data management agency. As of 10 p.m. Monday, 81 of the 647 online government services affected by Friday’s fire at the National Information Resources Service (NIRS) in Daejeon, about 140 kilometers south of Seoul, were back online, according to the government.

According to Yonhap News Agency, a full recovery is expected to take at least four weeks, given the time needed to relocate 96 damaged systems to the NIRS’ branch in the southeastern city of Daegu. To minimize public inconveniences, especially ahead of the extended Chuseok holiday, which begins Friday, the government has first restored services expected to be in high demand, including the postal and banking arms of the national postal service. Gov.kr, a major government portal for civil application services, has also been restored.

A police investigation is under way into the cause of the fire, which began after a lithium-ion battery exploded in a server room on the fifth floor of the NIRS and was completely extinguished Saturday.
