Fortnite servers will be going down for another round of maintenance soon, Epic Games has announced. The developer hasn't revealed how long the maintenance will last, but it's scheduled to take place tomorrow, July 19, at 1 AM PT / 4 AM ET / 9 AM BST and affects players on all platforms--PS4, Xbox One, PC, Nintendo Switch, and iOS.

Beyond the start time, Epic hasn't shared any further details on tomorrow's maintenance, but these periods are typically followed by a new batch of content for Battle Royale mode. That will likewise be the case tomorrow, as the second set of weekly challenges for Season 5 are slated to roll out on July 19.
