Update: Epic has sounded the all-clear on Fortnite, but the 50v50 Limited Time mode that was meant to be live today has been pushed back to next week. As a way of apology for all the trouble, the studio will hand out some freebies to players: A free Troll Stash Llama in Save the World and a Back Bling gift in Battle Royale this weekend, and then next week, a pack of Battle Stars for Battle Royale players and Seasonal Gold for Save the World players. A detailed post-mortem of what went wrong, and how Epic will (hopefully) avoid this kind of gong show in the future, is also on the way.
Thank you for your patience with the recent account issues, we're working on some goodies to show our appreciation! Info here (English Only for now) -https://t.co/KwVPGvfwssApril 12, 2018
Fortnite got Port-a-Fort grenades and a Replay system last night, but somewhere along the line it also suffered a database failure of some sort that caused problems for people trying to log into the game. Epic Games was forced to take it offline last night, and as of roughly 11 am ET today, there's still no ETA for its return.
We’re still undergoing extended instability and investigating the issues. Right now we don’t know how long it will take, but we will update you hourly. More info - https://t.co/DorRRH2eoHApril 12, 2018
Epic said it will update the status of the repair process hourly, and we'll let you know as soon as Fortnite is live again. You can also monitor the server situation at status.epicgames.com, and of course there's a Reddit thread filled with helpful advice.
