We would like to apologize once again to our customers, suppliers, and related parties for any inconvenience caused by the suspension of our domestic plants as a result of the malfunction in our production order system at the end of last month.
The system malfunction was caused by the unavailability of some multiple servers that process parts orders. As for the circumstances, regular maintenance work was performed on August 27, the day before the malfunction occurred. During the maintenance procedure, data that had accumulated in the database was deleted and organized, and an error occurred due to insufficient disk space, causing the system to stop. Since these servers were running on the same system, a similar failure occurred in the backup function, and a switchover could not be made. This led to the suspension of domestic plant operations. The system was restored after the data was transferred to a server with a larger capacity, and the plants resumed operation on August 29, 2023. We would like to report that we have identified the above as the true cause. Countermeasures have also been put in place by replicating and verifying the situation.
We would also like to reaffirm that the system malfunction was not caused by a cyberattack, and apologize to all parties for any concern this may have caused.
Going forward, we will review our maintenance procedures and strengthen our efforts to prevent a recurrence, so that we can deliver as many vehicles to our customers as soon as possible.
