SEGA’s own arcade games remain offline more than a week after unauthorized access forced the company to shut down ALL.Net and Aime, even as Bandai Namco machines have begun a limited return.
The outage started at 3:00 p.m. JST on November 1. In its initial disclosure, SEGA FAVE said a third party had accessed servers connected to the arcade network and player-card system. The company took both services down while it investigated the intrusion and checked the safety of its infrastructure.
A November 8 update brought the first real movement. Bandai Namco Experience said eight affected games could begin returning on a trial basis, including Taiko no Tatsujin, Mario Kart Arcade GP DX, Idolmaster Tours, and Mobile Suit Gundam Arsenal Base. Online play and card use may now work on those machines, although availability still depends on each location and title.
SEGA’s games are not joining them yet. The official ALL.Net service account said SEGA products remain under maintenance and still have no estimated restoration date. Its next progress report is due around 9:00 a.m. JST on November 10.
This Is Bigger Than Machines Going Offline
ALL.Net is the infrastructure underneath a large part of Japan’s connected arcade business. When it disappeared, players lost online functions, Aime card access, game-linked websites, location searches, and other title-specific services. SEGA also stopped PrizeON play, SEGA Lucky Kuji Online, and new SEGA ID registrations.
The outage reached the show floor, too. SEGA FAVE cancelled its Initial D The Arcade exhibition and Double Ace Cup plans at Amusement Expo 2026 because the network was still unavailable. A cyberattack on back-end infrastructure had become something players could see immediately: dark cabinets, cancelled events, and an arcade schedule suddenly built around what could still boot.
SEGA Is Dealing With Two Separate Security Incidents
This outage is not the same incident as the SEGA newsletter breach disclosed on November 9. As Geek Jack Music pointed out, that leak involved contractor Arara’s mailing platform and exposed more than 2.1 million email addresses. The ALL.Net and Aime investigation concerns SEGA FAVE’s arcade-network servers.
SEGA FAVE says its initial investigation found no evidence that customer or business-partner data had been taken from the affected arcade systems. Payment information, including credit-card data, was stored elsewhere and was not affected.
For now, Bandai Namco’s trial restart shows that parts of the network can come back. SEGA’s half remains the unresolved one. Players heading to an arcade should check the official account for the individual game before assuming its cabinet is online.
