Ubisoft had to shut down Rainbow Six Siege's servers and roll back transactions, a situation that came from a widespread breach that left various players with billions of in-game credits, ultra-rare skins of weapons, and banned accounts. As of Sunday, December 28, the status page on Rainbow Six Siege's website still shows "unplanned outage" on all servers across PC, PlayStation and Xbox. Later that evening, though, the company confirmed that it was done testing on the update it pushed out and was opening the severs back up to players. It also said that the transaction rollback was complete, but that the Marketplace would remain closed for the time being. ➡️ Our live tests are now complete and we are opening the game to all players. Please note that you may experience a queue when connecting, as our services ramp up. ➡️ The rollback is also complete. 🔸 Players who did not log in between December 27th 10:49 UTC and December 29th… https://t.co/mfaAVnvK5G — Rainbow Six Siege X (@Rainbow6Game) December 29, 2025 The fiasco began Saturday morning when Ubisoft said on X that they were "aware of an incident currently affecting Rainbow Six Siege" and "working on a resolution." A couple of hours later, the Rainbow Six Siege servers were shut down, following plenty of user reports showing either zero or billions in R6 credits, rare skins in their lockers and either account bans or unbans. Ubisoft later clarified Saturday afternoon on X that nobody would be banned if they spent their ill-gotten credits, but that a rollback of all transactions starting from Saturday, 6AM ET would soon be underway. On Sunday afternoon, Ubisoft informed the playerbase that they're currently performing a rollback, but that "extensive quality control tests will be executed to ensure the integrity of accounts and effectiveness of changes." The company added that "this matter is being handled with extreme care and therefore, timing cannot be guaranteed" and didn't provide an estimate for when servers would be back online. Update, December 29, 2025, 10:22AM ET: This story and its headline have been updated with the details about Ubisoft re-opening the game’s servers.
