Sega Fave, the Sega Sammy group company that operates Japan’s ALL.Net arcade network, suspended ALL.Net and the Aime player-card service at 3 p.m. on November 1 after confirming that a third party had gained unauthorized access to servers tied to both systems. The company disclosed the intrusion on November 2 and said its initial investigation had found no leak of customer or business partner information, and that payment data such as credit card numbers was not held on the affected servers.
ALL.Net, launched by Sega in 2004, handles online play, software updates, data logging and national leaderboards for networked cabinets. Sega titles on the network include maimai DX, CHUNITHM and Initial D The Arcade. Bandai Namco Experience licenses the same infrastructure for eight of its own titles, including Taiko no Tatsujin, Mario Kart Arcade GP DX and Mobile Suit Gundam Extreme VS. 2 Infinite Boost, so the shutdown spread well beyond Sega’s own machines. Bandai Namco cabinets can reportedly run offline for only about 72 hours before they must re-authenticate, and Taiko no Tatsujin machines stopped working altogether once the outage passed that limit.
Recovery is arriving in one direction only. Sega Fave said some ALL.Net and Aime functions were restored as of 9 a.m. on November 8, and Bandai Namco titles have been resuming in stages on a trial basis with online play and card use enabled. Sega’s own products remain under maintenance with online services unavailable, and the operator has set its next update for about 9 a.m. on November 10, with no date yet for a full restoration.
The incident is the second network failure in quick succession: the same service was taken offline for several days in late October over a separate exploit before reopening, according to gaming press coverage of the outage. Sega Fave has not said how the attackers got in, and no report has linked the November intrusion to ransomware.
