Toyota had to temporarily close 12 of its 14 auto assembly plants in Japan due to an unspecified system failure, resulting in 13,000 vehicles being “lost” per day.
Toyota announced that the problem arose during scheduled maintenance of the IT system on August 27, 2023. The purpose of the maintenance was to clean and remove fragmented data from the database. However, an error occurred that caused the system to stop when tasks reached the storage limit before completion.
This affected the functioning of the product ordering system and as a result the company was unable to plan and fulfill its production tasks. In particular, the use of the same infrastructure by the primary and backup servers caused the rapid transition to be prevented and the facility to come to a standstill.
The issue was resolved on August 29 when Toyota’s IT team prepared a larger server to host the partially migrated data; this server allowed the production system to recover and the plant to continue operating.
