NTT DOCOMO announced on November 11 that the nationwide difficulties using mobile phone services for subscribers of “5G SA (Standalone),” which had been occurring since 10:34 a.m. that day, were fully resolved at 7:17 p.m., approximately nine hours later. The cause was congestion at the switches accommodating 5G SA subscribers, the same as the outage on the 5th. No signs of unauthorized access or incidents indicating a cyberattack have been confirmed.
