On Saturday morning Pacific time, we suffered a global outage due to a sudden, significant surge in traffic. With that in mind, to explain whatвЂ™s been going on, weвЂ™ll be focusing on the downtimes experienced between Saturday October 9 to now. The global database also has a back-up in case the main fails. Most of your in-game actions are performed against this regional database because itвЂ™s faster, and your character is вЂњlockedвЂќ there to maintain the individual character record integrity. So to alleviate load and latency on our global database, each regionвЂ“NA, EU, and AsiaвЂ“has individual databases that also store your characterвЂ™s information and progress, and your regionвЂ™s database will periodically write to the global one. As you can imagine, thatвЂ™s a big task for one database, and wouldnвЂ™t cope on its own. First, thereвЂ™s our global database, which exists as the single source of truth for all your character information and progress. LetвЂ™s start at the beginning.Д«efore we talk about the problems, weвЂ™ll briefly give you some context as to how our server databases work. WeвЂ™re going to get a little bit into the weeds here with some engineering specifics, but we hope that overall this helps you understand why these outages have been occurring and what weвЂ™ve been doing to address each instance, as well as how weвЂ™re investigating the overall root cause. Our team, with the help of others at Blizzard, are working to bring the game experience to a place that feels good for everyone. This is not a complete solve to us, and we are continuing to work on this issue. A small number of players have experienced character progression lossвЂ“moving forward, any loss due to a server crash should be limited to several minutes. Tl dr: Our server outages have not been caused by a singular issue we are solving each problem as they arise, with both mitigating solves and longer-term architectural changes. We also want to give you some insight into how weвЂ™re moving forward. Since the launch of Diablo II: Resurrected, we have been experiencing multiple server issues, and we wanted to provide some transparency around what is causing these issues and the steps we have taken so far to address them.
