Arcades across Japan faced a week of partial silence after Sega Fave, Sega’s subsidiary for toys and arcade machines, detected unauthorized access to servers linked to the ALL.Net and Aime networks. Services were suspended at 15:00 on November 1, 2026, affecting both Sega titles and Bandai Namco games that rely on the same infrastructure.
What happened
According to Sega Fave’s official notice on November 2, third parties accessed some servers related to ALL.Net (the network connecting arcade machines for online play, updates and player data) and Aime (the card system that identifies players and stores progress). The initial investigation found no leak of customer or partner data, and payment information was not on the compromised servers. The company has not yet detailed how the access occurred or when it began.
The suspension hit online play, Aime card use, .NET services and some online lotteries. Affected titles include, from Sega, Initial D THE ARCADE, maimai DX and CHUNITHM; from Bandai Namco, Taiko no Tatsujin, Mario Kart Arcade GP DX and Mobile Suit Gundam Extreme Vs. 2 Infinite Boost, among others. Traditional offline machines continued to operate.
November 8 update
On November 8, ALL.Net operator informed that Bandai Namco titles would begin gradually resuming operation on a trial basis starting the same day, with online play and card use enabled. Sega services remain under maintenance with no estimated return date. The next update is scheduled for November 10 around 9:00.
Reports from ITmedia and Tom’s Hardware described arcade halls with rows of dark or silent machines in Tokyo and other cities. Tournaments were cancelled and some cabinets were removed from the floor. At Amusement Expo 2026, Sega withdrew its Initial D booth.
Why it matters
The episode highlights the risk of shared infrastructure in Japan’s arcade sector. A failure in Sega’s network impacted competitors’ games and left operators with no control over machine availability. For geek audiences, especially fans of rhythm games and racers like Initial D and Taiko, a week-long interruption means lost progress, cancelled events and reduced social experience in game centers.
Sega Fave has been transparent about the lack of a timeline and the absence of detected data leaks so far, but full restoration still depends on completing security checks.
