Sega suspends ALL.Net and Aime arcade services after cyber attack

Sega suspended services tied to its ALL.Net and Aime arcade networks from 3 p.m. on November 1, 2026, while it investigates a cyber attack and verifies system security. Sega said initial findings show no customer or business partner data exfiltration, and payment information including credit cards is managed separately and was not affected. Online arcade titles such as maimai, CHUNITHM and Initial D Arcade Stage are effectively unplayable, and the investigation is ongoing.
