Sega Arcade Network Outage Drags On After Unauthorized Access

A breach-linked outage of Sega Fave's ALL.Net and Aime services has kept arcade cabinets dark across Japan since November 1, with no recovery date announced.

An outage affecting the communication system that Sega Fave, based in Tokyo's Shinagawa ward, provides to game centers has now run for several days. As of 9 a.m. on November 6, there was no outlook for recovery. The cause is unauthorized access, according to the company.

The trouble began on the afternoon of November 1. In some arcades, rows of cabinets now sit with blank screens. The affected services include ALL.Net, which connects arcade machines to the network, and Aime, the IC-card-based user authentication system that identifies players and manages play data. The online lottery "Sega Lucky Kuji Online" and Sega's ID service are also hit.

As a result, games that rely on ALL.Net or Aime cannot be played normally. Venues have had to stop running them or offer them with restricted functions.

Not just Sega titles

At an arcade in the Kanto region visited on November 5, the damage extended beyond Sega games such as "Eiketsu Taisen". Bandai Namco titles including "Taiko no Tatsujin", "Mario Kart Arcade GP DX" and "Mobile Suit Gundam Extreme VS 2 Infinite Boost" were affected. Announcements on official game sites also list "Initial D THE ARCADE", "Wangan Midnight Maximum Tune 6RR PLUS", "CHUNITHM Mate", "maimai DX MAGiCAL" and "Mobile Suit Gundam Arsenal Base".

Similar scenes appear to be playing out nationwide. Posts on arcades' official social accounts show several venues halting or limiting games, some removing cabinets, and at least one canceling a planned tournament. Players have voiced frustration.

Not every machine is down: crane games at the visited arcade were running normally and drawing crowds.

Trade show impact

The outage has also reached the AMUSEMENT EXPO 2026 arcade trade show at Tokyo Big Sight, running November 6 and 7. Sega Fave has withdrawn its Initial D THE ARCADE exhibit. The company plans to post another update on ALL.Net's status on its official social account at around 9 a.m. on November 8.
