Toyota identifies cause of plant shutdowns

Toyota Motor has revealed the reason it had to stop production at its factories in Japan for two days last month, explaining that it was a problem with database capacity and not a cyberattack.

Toyota halted operations on August 29 at all 14 of its group domestic factories. A system failure had made it impossible to order parts.

Operations did not resume at all plants until the evening of the following day.

Company officials say maintenance work on August 27 produced an error because of insufficient disk space, which triggered a shutdown of the entire system.

It was not possible to switch to the backup system, because it was suffering from a similar problem.

Toyota says it will review its maintenance procedures and will improve safeguards to prevent similar problems in the future.
