According to Comicbook.com, Fallout 76 servers will go offline for an hour of scheduled maintenance.
Bethesda shared news of the update on Twitter.
But they won't be making any changes to the game, so don't expect patch notes.
Instead, Bethesda is pushing an update to improve server performance.
The down-time is slated to begin at 1:30 p.m. Eastern Standard Time on Nov. 21st.
Fallout 76 is the latest in the series, and the ninth title overall.
But unlike it's predecessors, Fallout 76 is an MMO, making it the first online multiplayer game for the series.
