For those hoping to start their Saturday off with some Rainbow Six Siege, you’ll be saddened to know that some unexpected Rainbow Six Siege down time is currently happening on all platforms as Ubisoft has confirmed issues with the title.

As of now, a majority of reports are coming in from users on the Xbox One version of Rainbow Six Siege, however, Ubisoft has stated that they are currently experiencing some network related issues across all platforms and multiple titles.

Hello everyone.

We’re aware of an issue currently affecting connectivity with our games and ability to access Cloud Save data on Uplay PC. We are working towards resolving this. We apologise for any inconvenience caused and appreciate your patience.

Update (15:56 UTC): We are still working to resolve the issue. Thank you again for your patience.

Please be sure to check this thread for future updates. Thanks!

At this time there doesn’t appear to be any kind of user-end fix, so for the meantime, for those that are experiencing issues, we will just have to wait until Ubisoft resolves the problem. We will be sure to update this post once the servers are back up.

In other Rainbow Six Siege news, a new patch has been deployed earlier this week that brought in the Year 4 Season 4.2 changes! Read up on that here.
