Following unauthorized access to its servers detected on November 1, SEGA Fave disabled several arcade network services in Japan, including the ALL.Net network and the Aime user authentication system. The outage impacted various titles from SEGA, such as maimai DX and Chunithm, as well as Bandai Namco games like Taiko no Tatsujin and Mobile Suit Gundam Extreme Vs. While initial investigations by SEGA Fave found no evidence of data leaks or compromised payment information, the disruption expanded to affect player data management, rankings, and software updates. By November 5, the outage caused significant operational issues for arcade centers across Japan. Some machines became unplayable due to expired license authentication, and operators reported financial distress and record-low revenue during holiday periods. As of November 8, 10, SEGA Fave has announced that there is currently no estimated time for the ~~gradual~~ full resumption of ~~trial operations for~~ ALL.Net and Aime services. While certain Bandai Namco ~~arcade titles. This restoration allows games such as~~ titles, including Taiko no Tatsujin, Mobile Suit Gundam Extreme Versus 2 Infinite Boost, and The Idolmaster ~~TOURS to support~~ TOURS, have begun a phased, experimental resumption of online play and card ~~usage.
