Sega's arcade network ALL.Net, and the Aime card system that sits on top of it, have now been offline for more than ten days after what operator Sega Fave calls unauthorised access by a third party. Services were switched off at 3 p.m. JST on November 1. In its November 12 update, posted at 9 a.m. JST on the official ALL.Net service account, Sega Fave said there was still no timeline for bringing Sega's own games back.
Bandai Namco's eight ALL.Net titles, including Taiko no Tatsujin and Gundam Extreme Vs. 2 Infinite Boost, restarted on a trial basis on November 8. Sega games such as maimai DX, CHUNITHM and Initial D The Arcade remain without online play or card use. The next status update is not due until about 9 a.m. JST on November 17, which is 8 a.m. in Malaysia and Singapore. That is a five-day gap, longer than the two-day rhythm of earlier updates.
What's confirmed
The breach. In its November 2 notice, Sega Fave said servers tied to ALL.Net and Aime were accessed without authorisation. It is still investigating whether any data was taken and how far the damage goes, and it shut the services down while it checks.
What Sega Fave says about your data. Its initial investigation found no leak of customer or business-partner information. Payment details, including credit card numbers, are not stored on the affected servers, so the company says they were not touched.
What stopped working. The notice lists online play for ALL.Net titles, store-location lookups on official game sites, each title's .NET web services, play using Aime cards, PrizeON, SEGA Lucky Kuji Online and new SEGA ID registrations.
Bandai Namco's trial restart. Game*Spark and ITmedia report that from the morning of November 8, eight Bandai Namco titles came back with online play and card use, including Taiko no Tatsujin, Mario Kart Arcade GP DX, The Idolmaster TOURS, JoJo's Bizarre Adventure: Last Survivor and Wangan Midnight Maximum Tune 6RR PLUS. Arcade staff were asked to power each cabinet on and check it before reopening it to players.
Why some cabinets went fully dark. Game*Spark reports that Bandai Namco's ALL.Net games can only run offline for up to 72 hours. Once licence checks lapsed, some Taiko machines could not be played at all, not even offline.
Sega's titles. Every Sega Fave update since, including the ones on November 10 and November 12, has said Sega products remain under maintenance with no restart date.
Background
ALL.Net, short for Amusement Linkage Live Network, is the backbone Sega launched in 2004 to connect arcade cabinets. Tom's Hardware notes it handles automatic updates, data logging, online play and national leaderboards. Aime is the IC card system that identifies players and keeps their progress, which is why rhythm games built around saved scores and unlocks, such as CHUNITHM and maimai, are hit hardest.
The outage also shows how much of Japan's arcade scene runs on one company's network. Bandai Namco licenses ALL.Net for many of its cabinets, so a problem at Sega took Taiko no Tatsujin down with it. Taito and Konami run their own networks and sign-in systems, so their cabinets were not affected.
My take: what it means for players
I'll be blunt: ten days is a long time for a network that rhythm and racing players treat like a save file. When an online console game goes down, you play something else. When your arcade card stops working, the score attack you've been grinding for months is frozen too. That hurts in Japan, and it hurts anyone in Southeast Asia whose local arcade runs Japanese ALL.Net cabinets.
The 72-hour offline limit is the part that should worry operators. It is meant to stop piracy, but it means a breach at one supplier can turn working machines into furniture. Sega and Bandai Namco will be asked about that rule once this is over, and they should be.
The good news is that Sega Fave says no customer or payment data has been found leaked so far. It is also checking properly instead of rushing back online. I'd rather wait another week than see a half-fixed network hacked again. It is the second long online blackout in under two weeks, after FromSoftware took Dark Souls II and III servers offline, and in both cases a slow, careful fix is the right call.
What we don't know yet
- When Sega titles return. Sega Fave has given no date; its next update is about 9 a.m. JST on November 17.
- Who did it and how. The company has not said who was behind the access or how it happened.
- Whether any data left. The investigation into exfiltration is still running; "no leak confirmed" is an early finding, not a final one.
- Lost progress or compensation. No word yet on extended events, refunds of paid features, or how missed ranking periods will be handled.
- Arcades outside Japan. Sega Fave's notices only talk about Japan, so it is not clear whether ALL.Net cabinets abroad are affected.

Sega Fave says its initial investigation found no customer data leak, and credit card and other payment details were not stored on the affected servers.
Is Taiko no Tatsujin back?
Yes, on a trial basis. Bandai Namco's eight ALL.Net titles, including Taiko no Tatsujin, restarted with online play and card use from November 8.
When will Sega arcade games come back online?
There is no date. Sega Fave's November 12 update gave no date either. The next status update is planned for about 9 a.m. JST on November 17.
