Starting at 4 a.m. ET / 9 a.m UTC, players will find Ghost Recon Wildlands down for a scheduled 2-hour maintenance period. During this time, all online sessions will be unavailable, including Ghost War multiplayer matches.
Once the maintenance period is over, Ubisoft will release patch notes which detail the “new content, changes and balancing.”
Here’s the official maintenance notice:
This Thursday from 9am UTC, we will operate a 2h maintenance in order to update our servers for the upcoming Update 1: Interference. In the meantime, we will update this thread regularly to let you know about the maintenance.
This maintenance will only impact the online sessions, including Ghost War. If you are already in a game when the maintenance starts, your session will be put to offline mode so that you can still be able to play the game solo with your 3 AI teammates.
The patchnotes will be available for you to read shortly after the maintenance is over, listing the new content, changes and balancing.
Keep your eyes on MP1st for future updates!
