On December 13, the Ministry of Internal Affairs and Communications gave administrative guidance to provide a stable service in response to communication failures of Rakuten Mobile.
Rakuten Mobile offers a communication service for nearly 5,000 people who were selected by lottery as a “Free Supporter Program” from October 1. However, this is a service that is deployed upon receiving a license from the Ministry of Internal Affairs and Communications and is subject to administrative guidance by the Ministry of Internal Affairs and Communications in the event of a serious communication failure.
This time, a communication failure occurred on December 10. According to Rakuten Mobile, voice calls and data communications were unavailable or difficult for some users over 2 hours and 45 minutes. About the cause, Rakuten public relations explained, “It is due to software defects in some of the facilities that control billing and calls on the network.”
The Ministry of Internal Affairs and Communications requested Rakuten Mobile to conduct a network durability test, network monitoring system, and dissemination to users. We are requesting that Rakuten develop a specific plan and report it to the Ministry of Internal Affairs and Communications.
Sanae Takaichi, Minister of Internal Affairs and Communications, at a regular conference on the 13th, “After promptly investigating the full cause of the accident and instructing the clerical staff to take firm measures to prevent recurrence”And comments. We ask Rakuten for the user's profit (that is, to be able to use the service for granted).
Rakuten told Engadget ’s interview with the Ministry of Internal Affairs and Communications, “I deeply apologize for any inconvenience caused to customers due to network problems. I will continue to make improvements. ”
Rakuten's mobile service on its own line sells “complete virtualization”, which deploys most of the mobile phone base station equipment on general-purpose server equipment. I often appealed to those who are strong.
Regarding Rakuten, there is another issue that the construction of the base station is delayed, and the Ministry of Internal Affairs and Communications provides administrative guidance three times in March, July, and August. Because of this communication failure, Rakuten has received the fourth administrative guidance while it is virtually unable to develop "commercial services."
Due to a communication failure of less than 3 hours in a substantial pre-service environment, trust in the “stable network” that Rakuten has differentiated from other companies is shaking.
