Sega ALL.Net network outage impacts Japanese arcade centers

Arcade game centers across Japan are facing severe operational disruptions following unauthorized access to Sega Fave’s ALL.Net and Aime network services. The security incident, which began around November 1, has forced the suspension of various online and offline services, including player data management, rankings, and software updates.

The outage affects numerous popular titles from both Sega and Bandai Namco Experience, such as Taiko no Tatsujin, Mobile Suit Gundam Extreme Vs., and Mario Kart Arcade GP Deluxe. While some games allow limited offline play, many have become unplayable after license authentication expired following the initial disruption.

Arcade operators have reported significant financial distress, with some noting record-low revenue during holiday periods. The ongoing maintenance and service suspension have left many machines with dark screens, leading to concerns regarding the long-term viability of local gaming centers.
