A racing cabinet can still have its steering wheel, pedals and screen working perfectly, yet lose some of its most important features when a remote server goes offline. That is the problem facing Japanese game centers during the SEGA arcade outage, which has interrupted online functionality across multiple popular games.
What makes this disruption particularly significant is its reach beyond SEGA’s own catalog. Bandai Namco titles also depend on the affected infrastructure. Consequently, an incident involving one company’s servers has become a much wider problem for arcade operators and players.
SEGA FAVE confirmed on November 2, 2026, that a third party had accessed servers associated with its ALL.Net network and Aime player-card system without authorization. Related services have been suspended since 3 p.m. Japan Standard Time on November 1, with no confirmed restoration date.
Why the SEGA arcade outage affects more than online matches
Modern arcade machines are not necessarily independent devices. Many communicate with central servers to authenticate players, retrieve saved progress and provide connected features. This arrangement makes it possible to return to a familiar game at another participating location without starting from scratch.
ALL.Net provides network connectivity for compatible arcade titles, while Aime allows players to identify themselves using a card and access supported game data. Depending on the title, that information can include records, scores, progression and other personalized features.
However, this convenience creates a shared dependency. When central services become unavailable, several otherwise unrelated games can lose functionality simultaneously. The problem is therefore not simply that competitive matchmaking has stopped. For some machines, the usual way of loading a player’s session is unavailable too.
That distinction matters in a country where arcade gaming remains closely associated with repeat visits, personal records and dedicated communities. Players may spend considerable time developing their skills and maintaining progress across sessions. An interruption to the systems supporting those activities changes the experience even when a cabinet can still run locally.
Initial D and Taiko no Tatsujin show how far the disruption reaches
Two particularly recognizable affected games are Initial D THE ARCADE from SEGA and Taiko no Tatsujin from Bandai Namco. According to Kotaku, some arcade locations have switched compatible machines into offline mode to keep them playable, while other affected cabinets have been unavailable.
Offline operation is an important distinction. It may preserve basic gameplay on supported machines, but it does not automatically restore online competition, account-based features or normal progression synchronization. Furthermore, availability can differ between individual games and locations.
Bandai Namco Experience has independently confirmed that its ALL.Net-compatible titles are affected. Its published list includes Mario Kart Arcade GP DX, Idolmaster TOURS, JoJo’s Bizarre Adventure: Last Survivor and Mobile Suit Gundam Extreme Vs. 2 Infinite Boost, alongside Taiko no Tatsujin and other games.
For players, the practical advice is straightforward: check a game’s official service notices or contact the arcade before traveling. SEGA has also suspended official arcade location listings for ALL.Net-compatible titles, removing one of the usual ways to find participating machines.
The incident is a reminder of how arcade gaming has evolved. SEGA’s fighting-game heritage, also reflected in its more recent Virtua Fighter revival plans, comes from an era when individual cabinets were central to the experience. Today’s connected arcade ecosystem offers much more persistent functionality, but also introduces infrastructure dependencies that earlier machines did not share.
A second interruption after October’s security maintenance
The timing adds another layer to the story. Kotaku reports that SEGA had already taken the affected services offline for several days in late October to address a vulnerability. Following that maintenance period, access reportedly returned with restrictions limiting the services to Japan.
Now, another shutdown has followed. However, there is no confirmed public evidence establishing that the earlier vulnerability caused the newly disclosed unauthorized access. Treating both events as a single attack would go beyond the information currently available.
SEGA FAVE, headquartered in Shinagawa, Tokyo, is investigating how extensively its systems were affected and whether information was removed. Its initial findings have not identified any leak involving customer or business partner data.
There is also an important distinction concerning payments. The company states that credit card details and other payment information are stored separately from the affected servers and were not impacted by this incident. Nevertheless, investigators have not yet completed their assessment of the broader intrusion.
Beyond arcade gameplay, suspended services include PrizeON, SEGA Lucky Kuji Online, new SEGA ID registrations and the individual .NET services associated with compatible titles. This wider list illustrates how several digital products can depend on connected systems even when they serve different audiences.
What players should expect before ALL.Net and Aime return
There is currently no official timetable for restoring normal operation. SEGA FAVE says its investigation and security verification will require additional time. The company plans to publish updates through its corporate website and the individual services once a decision about reopening has been made.
Importantly, a lack of confirmed data theft does not mean every security concern has been resolved. Before restoring access, operators need sufficient confidence that affected systems can operate safely. That helps explain why a service interruption may continue even when no financial information has been compromised.
For regular players, the biggest unanswered questions concern when their preferred machines will return to normal and which features will be available immediately. SEGA has not announced that existing Aime progress has been erased. Equally, the company has not provided a complete account of how every game will behave once connectivity is restored.
Until more information becomes available, players should avoid assuming that an offline machine offers the same progression features as its connected version. Individual game notices remain the most reliable way to check which functions are supported during the interruption.
Arcade operators face a different challenge. Machines that cannot offer their normal services may become less attractive to customers, particularly when games depend heavily on persistent records or competitive features. Offline modes can reduce that disruption, although they are not a complete substitute for the connected experience.
SEGA FAVE has apologized to customers and business partners and promised stronger information security measures. Readers can follow the latest confirmed information through the official SEGA FAVE security notice.
Ultimately, the SEGA arcade outage highlights a vulnerability of modern arcade entertainment: physical machines increasingly rely on online systems that players rarely see. Their convenience becomes especially noticeable when those systems disappear. The immediate priority is restoring safe access, but the longer-term question is whether connected arcade games can offer better alternatives when their networks fail.
