In response to KDDI's large-scale communication failure last month, the Ministry of Internal Affairs and Communications issued administrative guidance to the company on the 3rd to instruct the company to prevent recurrence.
Until now, administrative guidance on communication failures has been given in the name of the bureau chief, but the Ministry of Internal Affairs and Communications has given it for the first time in the name of the minister, citing the serious impact it has had on socioeconomic activities.
After that, I asked them to report the implementation status of the recurrence prevention measures by November 10.
In KDDI's communication failure, it became difficult to use voice calls and data communications for more than two and a half days nationwide, and the number of affected users, including subsidiaries, reached a total of more than 30.91 million people, the largest ever.
