Sega Server Outage Disrupts Japanese Arcades
The sensory overload typically experienced when visiting video game arcades in Japan was eerily absent from some venues this week. Reports indicate that a Sega system outage left rows of screens blank. However, arcade network operator ALL.net confirmed that both Sega and Bandai Namco machines are affected, with impacted venues gradually resuming operations on a trial basis.

The Role of the ALL.Net Network
ALL.Net, short for Amusement Linkage Live Network, was launched by Sega in 2004 to handle auto updates, data logging, online play, and national leaderboards for arcade titles. Sega games such as Initial D The Arcade, Maimai, and CHUNITHM rely on this network, alongside Bandai Namco titles like Taiko no Tatsujin, Mario Kart Arcade GP DX, and Gundam Extreme Vs.
Investigation and Partial Restoration
In an official blog post, ALL.Net and Sega Fave reported suspending services after detecting unauthorized access by a third party. The company assured customers that personal information and billing data were not stored on the compromised server, though additional time was requested to complete safety checks before a full restoration.
Bandai Namco titles have begun a phased return with online play and card use enabled. Meanwhile, Sega products remain under maintenance with unavailable online services. A formal news bulletin regarding the ongoing resolution is scheduled for release.
Classic offline arcade machines remain unaffected by the incident. Rival arcade operators Taito and Konami utilize separate, independent networks and authentication systems that continue to operate normally.
