Sega arcade network outage leaves Japanese arcades quiet for a week

For one whole week, Sega's network in Japanese arcades were unavailable to play on. This means gamers couldn't enjoy their digital services and games that require cards. This was a big deal for arcade gamers as a big part of their day was interrupted by this outage.

And this is for the ALL.Net services. The place where online services and loyalty programs are used. It was big for Sega arcade gamers, but the rest of the arcade scene was barely affected during the outage.

What was offline was the ALL.NET network. That's where the online stuff for Sega arcade games works. And according to the operator of ALL.NET, there was an unauthorized access from another party to the system.

Because of this security breach, Sega had to take their online services down to contain the situation and secure their servers. As of November 3, 2026, Bandai Namco arcade games are back up and running, on a trial basis.

That means gamers can enjoy online services and play with cards for those titles. They're back to doing their thing.

The Sega titles are still down on maintenance, but there's no time set for the repair. Sega is promising to release a news bulletin on November 10th where they'll give their customers an update on what's going on.

Good to know personal information and billing data isn't stored on the server that was hacked. Also, classic offline arcade games and other arcade networks like Taito and Konami's weren't affected by this.

A social media user posted images on how things were looking. The strange fact that you see a "quiet" local arcade during this blackout.

With some Bandai Namco titles being online again, that's a relief to those players of those titles. For Sega users, it's still a waiting game as to when their favorite games will be online again.
