Rainbow Six Siege Outage: Ubisoft Brings Severs Online After Massive Backend Breach
Ubisoft has begun rolling back player data after a major breach disrupted Tom Clancy’s Rainbow Six Siege, but has not shared a timeline for server restoration. The attack forced a global shutdown after in-game systems were manipulated, causing account issues, in-game economic disruption, and random bans. Ubisoft says the rollback is being handled carefully, followed by extensive quality checks. Servers across PC and consoles remain offline, leaving many players locked out while investigations and system integrity checks continue.
