You’re leaning forward, thumb on the joystick or fingers hovering over WASD, ready to execute a perfect pixel peek on Bank. Then it happens. The screen freezes, the dreaded "Connection Failure" icon pops up, and you're booted back to the main menu. It’s frustrating. It’s annoying. Most importantly, it makes you wonder: is Rainbow Six Siege down for everyone, or is your local ISP just having a meltdown?
Ubisoft's tactical shooter is a beast of a game, but its infrastructure can be finicky. Between the seasonal updates like Operation Collision Point and the constant backend "maintenance" that seems to happen at the worst possible times, server stability is a moving target. If you can't get into a match, don't start reinstalling your 80GB game client just yet. Most of the time, the issue is on Ubisoft's end, and there are specific ways to verify that before you go crazy resetting your router.
Why Rainbow Six Siege keeps going offline
Server outages in Siege aren't always a "total blackout." Sometimes the shop is down. Sometimes the matchmaking works but the "Squad" system is broken, leaving you unable to invite friends. The game relies on a complex web of Azure servers and Ubisoft’s proprietary middle-ware. When one piece of that puzzle chips, the whole thing feels broken.
Often, the servers go down because of High Traffic. When a new season drops, or a popular streamer hosts a massive tournament, the login servers get hammered. Ubisoft’s servers sometimes struggle to authenticate thousands of players hitting the "Connect" button at the exact same millisecond. It’s a bottleneck. Honestly, even ten years into this game's life cycle, the infrastructure still feels a bit like it’s held together by duct tape and prayers during peak hours.
Maintenance is the other big culprit. Ubisoft usually schedules these for Tuesday mornings or during mid-season patches. They usually take about an hour, but as any veteran player knows, "one hour" can easily turn into three if the deployment hits a snag. If you see a "Server Maintenance" pop-up, there's literally nothing you can do but wait and maybe watch some old Pro League VODs to keep your aim sharp.
How to check if Rainbow Six Siege is down for everyone
Don't trust the in-game notification entirely. Sometimes it lags behind reality. To get the fastest update, you need to go where the data is actually live.
- The Official Ubisoft Help Twitter (X): This is usually the first place they post. If a global outage occurs, @UbisoftSupport will tweet it out within 15 to 20 minutes. They’ll use terms like "degradation" or "unplanned downtime."
- The Siege Status Page: Ubisoft maintains a dedicated Rainbow Six Siege Status website. It breaks down connectivity by platform—PC, Xbox, and PlayStation. If the bars are green, the problem might be on your end. If they're red or yellow, the servers are definitely struggling.
- DownDetector: This is the "people's choice" for checking outages. It doesn't rely on official corporate word; it relies on player reports. If you see a massive spike in the graph within the last 10 minutes, the Rainbow Six Siege down reports are likely accurate.
- The R6 Reddit: Refresh the "New" tab on r/Rainbow6. If the game is down, you’ll see twenty posts saying "Servers down?" within seconds. It's the fastest way to confirm if a specific region, like US East or EU West, is having issues.
Common error codes and what they actually mean
Siege loves its alphanumeric codes. Seeing [3-0x0001000B] is enough to give any long-term player a headache. Most of these boil down to "we can't talk to the server," but a few are specific.
The 6-0x00001003 error is a classic. It usually points to a timeout. This happens when your client sends a request to the Ubisoft servers, and the server is too busy to answer. It doesn't mean your internet is dead; it means the line is busy.

Then there's the dreaded "Update Rate" or "Latency" icons in the top right corner of your HUD. If you see these flickering red while you're in a match, the server is "desyncing." This is arguably worse than the game being down entirely because it leads to "ghost bullets" where you shoot a Hibana in the head, but the server decides she was actually three feet to the left. When the Rainbow Six Siege down status is "Partial Degradation," this is exactly what you experience.
Fixing it on your end (When it’s not Ubisoft)
Let's say the status page is green, Twitter is silent, and your friends are all playing without you. Now the ball is in your court.
First, do a hard cold boot. If you're on console, don't just put it in "Rest Mode." Turn it all the way off, unplug the power cable for 30 seconds, and plug it back in. This clears the system cache and often force-refreshes your connection to the Ubisoft Connect data centers. On PC, closing the Ubisoft Connect client via Task Manager is a mandatory first step. It often hangs in the background, trying to authenticate a session that has already timed out.
Flush your DNS. This sounds technical, but it’s basically just giving your PC a fresh map of the internet. Open Command Prompt, type ipconfig /flushdns, and hit enter. It’s a magic fix for many "Server Connection Failed" errors that happen right at the title screen.
Check your NAT Type. Siege is notoriously picky about this. If your NAT Type is "Strict," you’re going to have a hard time connecting to other players. You want it "Open." This usually involves going into your router settings and enabling UPnP (Universal Plug and Play). If that's already on, you might need to manually forward ports. For Siege, the common ports are:
- TCP: 80, 443, 13000, 13005, 13200, 14000, 14001, 14008, 14020, 14021, 14022, 14023, 14024
- UDP: 6015
The hidden "Ubisoft Connect" factor
Sometimes the game itself is fine, but the Ubisoft Connect overlay is the culprit. This happens more on PC than consoles. If the overlay fails to sync your cloud saves or fails to load your friends list, it can prevent the game from reaching the main menu.
Try disabling the overlay in the Ubisoft Connect settings. It’s a lightweight fix that has solved the "infinite loading screen" for thousands of players. You lose the ability to invite friends easily via the Shift+F2 menu, but at least you can actually get into the game. Once you're in, you can usually use the in-game "Invite" buttons which rely on different API calls.
What to do while the servers are toasted
Honestly? Take a break. Siege is a high-stress game. If the servers are down, it’s a sign from the universe to go grab a glass of water or stretch your wrists.
If you're desperate for a tactical fix, you can usually still play "Situations" or the "Shooting Range" offline. These don't require a constant ping to the matchmaking servers. It’s a good time to practice your recoil control with those high-skill guns like Twitch's F2 or the SMG-11.
Check for an update. On Steam or the Ubisoft Store, sometimes a small 100MB hotfix gets pushed out. If you don't have that tiny update, the game will refuse to connect to the "Live" servers, and it won't always tell you why. It’ll just say "Server Connection Error." Manually checking for updates is a pro move that catches these silent blocks.
Moving forward: Stay ahead of the outages
Connectivity issues are part of the Siege experience. It’s the tax we pay for a game with fully destructible environments and complex physics that have to be synced across ten players in real-time.
To stay prepared for the next time Rainbow Six Siege is down, keep a shortcut to the Downdetector page on your phone. It saves you the 10 minutes of "Is it me or them?" anxiety.

Next Steps for Players:
- Bookmark the Ubisoft Support Twitter: It is the only place with "official" timestamps for when servers will return.
- Set a Static IP: If you're on a PC, setting a static IP and manually configuring your DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1) can bypass many regional routing issues.
- Check your Ethernet: If you're playing on Wi-Fi, Siege will drop you. The game’s packet loss tolerance is incredibly low. A $10 LAN cable is the single best "buff" you can give your connection stability.
- Monitor the "R6Fix" Portal: If you encounter a bug that boots you from matches consistently, report it there. Ubisoft developers actually use that data to prioritize backend fixes.
Stop fighting your router if the global reports are spiking. Just wait for the green light, and then get back to defending that objective.
