Latest Verified Status:
As of Sunday, Dec 28 2025, Rainbow Six Siege servers remain offline worldwide with no official ETA for restoration. Ubisoft has taken the multiplayer service and in‑game Marketplace completely offline following a serious security breach that disrupted gameplay, account integrity, and virtual economies.
What’s Happening with Siege Servers?
Rainbow Six Siege (R6) remains down worldwide due to a confirmed security incident. Ubisoft has acknowledged abnormal activity — including massive unauthorized credits, strange in‑game ban messages, and suspicious account changes — and is actively managing a rollback of affected transactions while the servers stay offline. There is no published timeline yet for when full access will return.
What Triggered the Outage?
1. Exploit / Hack Activity Detected
Players began reporting that their Siege accounts were suddenly credited with billions of R6 Credits, Renown, Alpha Packs, and rare cosmetics without purchase or gameplay. Some accounts also showed random bans and unbans, including high‑profile streamers and influencers — a clear sign of unauthorized access.
This isn’t merely a server crash — it reflects active manipulation of live service systems, not normal maintenance or planned downtime.
2. Ubisoft Response so Far
Ubisoft’s official Rainbow Six Siege account on X (formerly Twitter) issued multiple updates:
- Confirmed an ongoing incident affecting the game.
- Confirmed intentional shutdown of Siege and the in‑game Marketplace to contain the situation.
- Stated nobody will be banned for using the unauthorized R6 Credits.
- Announced a rollback of all transactions since ~11:00 AM UTC when the issue began.
No further technical breakdown has been released yet by Ubisoft. There’s also no estimated time of arrival (ETA) for the servers to come back online.
Why This Matters to Players
Economy & Progress Risk
An exploit that adds billions of premium credits and currency can massively distort Siege’s in‑game economy and ranking progression. Players are rightfully worried that:
- Illegitimate currency may be removed during rollback.
- Inventory items obtained during the incident may disappear.
- Competitive ladders and profiles could be reset if corrupted.
Community voices strongly discourage players from attempting to log in or use the unauthorized credits until official confirmation from Ubisoft that systems are secure and stable.
Security & Data Concerns
While Ubisoft hasn’t confirmed a leak of personal data or source code, independent reports and community speculation suggest the exploit might be linked to a backend system vulnerability (e.g., a database flaw like MongoDB bugs similar to “MongoBleed” types), allowing unauthorized manipulation of user data and game logic. This remains unverified by Ubisoft but is being widely discussed in security communities.
Key point: At this time, no verified official bulletin confirms internal database compromise or code leakage — only that the incident has caused severe disruption.
Is MongoBleed Involved? (Technical Rumors)
There are rumors among cybersecurity circles about a severe MongoDB vulnerability (CVE‑2025‑14847) that could let unauthorized attackers access uninitialized memory and potentially pivot deeper into affected systems — sometimes referred to loosely as “MongoBleed.” This has been widely discussed in security news, but as of now Ubisoft has not publicly confirmed any link between that specific flaw and the Siege outage.
Translation: There’s plausible buzz about backend database vulnerabilities being exploited, but no verified Ubisoft statement confirming the precise method used by attackers.
Current Server Status (Community & User Reports)
Player reports from official subreddits indicate:
- Siege login attempts currently fail with connection errors.
- Matchmaking, ranked, quick match, and other multiplayer services are inaccessible.
- Some users note disrupted or unusual account states (reset levels, inflated credits, missing items).
- Players are anxiously awaiting official updates.
These community signals align with Ubisoft’s action of taking all services offline.
Timeline of the Incident (Verified)
| Date/Time (UTC) | Event |
|---|---|
| Dec 27 Morning (~11:00) | Reports of unauthorized credits & exploits begin. |
| Afternoon | Ubisoft posts initial awareness message. |
| Later Dec 27 | Siege & Marketplace taken offline. |
| Dec 28 (Today) | Servers remain down with rollback in progress, no ETA. |
This progressive escalation underscores that this is not routine downtime.
What Players Should Do Right Now
✔ Avoid logging in until Ubisoft confirms the servers are stable.
✔ Do not spend any credits or renown gained during the outage window.
✔ Avoid marketplace transactions — these may be rolled back or flagged.
✔ Keep an eye on Ubisoft’s official social channels for verified updates.
✔ Consider changing your Ubisoft account password if you see unusual activity (good security practice).
These steps protect your account integrity while the incident is being resolved.
What We Still Don’t Know (Yet)
❓ Exact attack vector: Ubisoft hasn’t specified how the breach happened.
❓ Extent of potential data access: No official confirmation of personal data leakage or source code exposure.
❓ ETA for service restoration: Ubisoft has provided no timeline.
❓ Final rollback impact: How far Ubisoft will rewind account states remains to be seen.
These unknowns are critical — and only Ubisoft’s security team can resolve them with precision.
Conclusion
The Rainbow Six Siege outage on Dec 28 2025 is not a simple server maintenance issue — it’s a major security incident with far‑reaching implications for the game’s live services, player economies, and community trust. Servers are still down worldwide as Ubisoft continues a rollback process to neutralize the exploit and restore system integrity. There is no confirmed ETA for a full return.
Editorial perspective: This incident underscores the fragility of live‑service gaming ecosystems in the face of sophisticated backend exploits. Ubisoft’s rapid rollback strategy (while disruptive) is the correct priority to preserve the competitive and economic balance — but transparency around root cause and timeline will be essential to rebuild player confidence once systems come back online.
