Rainbow Six Siege servers are currently down as Ubisoft implements patch 5.0 and the Operation Red Crow expansion to players. Server maintenance is expected to take four hours, and if all goes well, the game will be back up with the new content at 1 p.m. ET / 10 a.m. PT.

If you have purchased Red Crow, you will be getting two new Operators, and several new weapon skins. In addition, everyone will have access to a new Skyscraper map, as well as all the bug fixes, balancing. matchmaking and some new features. The official site has a complete rundown of all the changes.

Ubisoft just recently announced that new content for the game will not end with Operation Red Crow, but continue on for another full year.
