Fortnite's free-to-play Battle Royale mode has surged in popularity over the past few weeks, recently hitting a new record of 3.4 million concurrent users. Unfortunately, the influx of players has also resulted in a number of server issues across PS4, Xbox One, and PC, which developer Epic has addressed in a new post on its website.

"We were not able to stay ahead of our continued growth and multiple of our backend services have been struggling under load the last several weeks. And we also shipped v2.3.0 with significant bugs. We don't consider either acceptable," Epic wrote. As a result, the developer says it has "changed [its] release plans [and] processes to help improve quality of client builds."
