Japan's second largest mobile operator has a large -scale failure

The reporter came to a mobile phone store under KDDI. After the communication fault, many users poured into the KDDI store to ask the fault, or the Wi-Fi signal in the store surfed the Internet. The reporter himself is also a user. Since the early morning of the 2nd, KDDI users have displayed no signals and unable to call calls on their mobile phones, and their mobile phones are also good and bad.

According to Kyodo News, Japanese telecommunications operator KDDI announced that at about 12 noon on July 3 local time, the recovery of mobile communication failures in western Japan has been completed. However, measures to limit communication volume are still continuing, and the comprehensive recovery time of the line has not been determined.

About 39.15 million mobile phone user communication is affected

As the second largest mobile operator in Japan, the number of mobile phone users under KDDI is about 31 million. In addition to other operators renting the company's line, the number of affected users is about 39.15 million, which is equivalent to Japan. About 1/3 of the population. Because the failure also caused the relevant users to call the emergency call, the Japanese Fire Department and others called on the public to use a fixed phone or public phone to ask for help. In addition to mobile phone communication, the failure has also affected other infrastructure in other aspects.

Communication faults affect a large number of infrastructure in Japan

Under the circumstances of the typhoon gradually approaching Japan, nearly 40 % of Japan's about 1,300 meteorological observation points across the country were affected by the failure and unable to transmit data. In addition, some banks' automatic withdrawal machines, bus system ride cards, and some networking services of car companies such as Toyota cannot be used. The logistics information system of railway freight is also affected, causing logistics delay, and email and package delivery may be delayed.

This morning, the Minister of General Affairs of Japan said that the communication failure has constituted a major accident identified by Japan Telecom's relevant regulations.

In fact, this is not the first time that this happened in Japan. In October last year, Japan's largest mobile operator NTT Domo Momo also had 29 hours of communication failure, and about 1 million people were affected. The two mobile giants have suffered a large -scale communication failure one after another, which also shaken Japanese consumers' trust in related companies.
