Following Diablo 4’s server slam weekend, Blizzard says that it’s ready for the game’s launch.

Speaking to GamesRadar+, Diablo general manager Rod Fergusson said, "We learned a lot from each [beta test]. We're feeling better, like we feel good about that, like all the stuff that we've learned."

Diablo 4's latest beta test ran from May 19 to May 21 with the express purpose of testing server load, hence the "server slam" moniker. There were few reports of issues during the test, which explains Fergusson's optimism, although he notes that you can "never" truly be 100 percent ready for a game launch the size of Diablo 4. He likened launch day to the opening of an amusement park; if a million people show up, it doesn't matter how prepared you are, there simply won't be enough space for everyone to get in.

"We've done the work we could do to make launch day as smooth as possible. And we feel good about where we are," Fergusson added. "We've done the work, and we've done a lot of testing, and so we're prepared. But you know, never say never. It might be a little bumpy on the first day, but our hopes are that, like we did on those weekends, we learn and adapt."

Fans still remember Diablo 3's disastrous launch and the dreaded "error 37." For days following Diablo 3's release, players were unable to connect to the game's servers due to the massive amount of traffic all crowding in at once. And because Diablo 3 required users to verify their games with a central server, you couldn't even play solo in offline mode.

Diablo 4 will have similar requirements, raising the specter of a similar situation happening again. Much of Diablo 4's earliest beta tests were plagued with server issues such as long login queues and random disconnects as Blizzard's servers struggled to keep up with player demand. Those issues lessened over the course of those beta tests, but as Fergusson said, you never know until launch day.

Diablo 4 arrives on June 6 for Xbox Series X|S, Xbox One, PS4, PS5, and PC. Deluxe and Ultimate Edition pre-orders get access on June 1.

Besides trepidation over Diablo 4's launch day, Blizzard is also under fire for hosting a Q&A session where many of the questions seemed to have been posed by fake social media accounts. Following the livestream on May 25, a Twitter user did some sleuthing and found that many of the accounts that supposedly asked questions during the stream didn't exist until after the video was posted or never asked those questions in the first place. A bizarre blunder for Blizzard.
