Eighteen hours have passed since the fire at the Daejeon National Information Resources Service (NIRS) was fully extinguished, but Post Office financial functions remain paralyzed. Prime Minister Kim Min-seok asked for systems directly tied to economic activity, such as Post Office finance, to be restored as quickly as possible, but they have not yet returned to normal.
When you access the Post Office app on the 28th, only the message "Cannot connect to the network" appears. For Post Office finance, all services—including deposits and withdrawals, transfers, automated teller machine (ATM) use, and insurance premium payment and payout—are suspended. Cross-bank account verification, funds claim and return processing, and open banking are also unavailable. As these services are used in earnest when weekdays begin, delays in restoration could lead to additional damage.
Websites of financial government agencies, including the Financial Services Commission, are still inaccessible. Even when accessing major bank apps, a notice appears saying, "Due to the government's emergency service inspection, some services may not function smoothly."
According to financial authorities, the suspended financial services include identity verification procedures such as checking the authenticity of resident registration cards, services linked to administrative agencies such as internet Giro and fee payments, and financial services linked to the Post Office.
Major banks are also notifying users that services may not function smoothly for passport and foreigner registration card authenticity verification, Gukmin Biseo, mobile verification of resident registration cards, electronic certificates, the digital open service, and public my data. However, authenticity verification remains possible for mobile IDs issued before the disruption and for physical driver's licenses. Some financial companies also said that the service to change the usage area for people's livelihood recovery consumption coupons may not function smoothly.
Financial authorities held an emergency response meeting the previous day and asked financial companies to "provide detailed information on specific financial service disruptions and alternative transaction methods so that people do not experience inconvenience due to anticipated financial service disruptions."
According to the Central Disaster and Safety Countermeasures Headquarters at the Ministry of the Interior and Safety, around 5 a.m. that day, the constant temperature and humidity units in data centers 1–6 at the NIRS were restored and began operating. The units maintain the temperature and humidity of data centers at a certain level, and when they failed due to the fire, the power to servers was shut down to prevent data loss, suspending 647 government work systems.
As of 7 a.m. that day, the headquarters said it had activated more than 50% of network equipment and restarted 763 of 767 core security devices. A headquarters official said, "Given the current progress, we expect to sequentially restart 551 services during the day and check whether they are operating normally." However, it is expected to take time to restore the systems in data center 7-1, which was directly affected by the fire.
