Tokyo, Nov. 11 (Jiji Press)–NTT Docomo Inc. said Wednesday that a disruption to its mobile phone network, which began earlier in the day, had been fully resolved. The major Japanese mobile carrier said the disruption was caused by a switching system that processes signals from base stations failing to operate normally. It said it had found no evidence of unauthorized access or a cyberattack. A similar network disruption occurred at NTT Docomo on Thursday last week, but it is unclear whether the two incidents are related. The latest disruption began around 10:30 a.m. Wednesday, affecting the carrier’s 5G Standalone high-speed, high-capacity telecommunications network service. Users experienced difficulties making calls and accessing data services. Service gradually returned to normal from around 4:30 p.m. and was fully restored at around 7:20 p.m. NTT Docomo also attributed the last week’s disruption to a switching system malfunction. On Friday, NTT Docomo President Yoshiaki Maeda apologized at a press conference after personal information on about 300,000 people held by the carrier was compromised through unauthorized access.
