Update 11/24/2021: The DDoS attacks referenced in this article have now subsided.
Original article: Players are experiencing issues with Activision Blizzard's battle.net, and according to Blizzard, the cause of the issue is an ongoing DDoS attack. Battle.net is Activision Blizzard's launcher that allows them to access Overwatch, Call of Duty: Warzone, Diablo, and other Blizzard online titles from the company.
Battle.net stated on Twitter, "we are currently experiencing a DDoS attack, which may result in high latency and disconnections for some players. We are actively working to mitigate this issue."
A Distributed Denial of Service attack occurs when an individual or group of individuals overwhelm a server with requests for traffic, crippling its ability to send and receive data. Blizzard has experienced numerous DDoS attacks on their servers over the years, including high-profile attacks on WoW: Classic shortly after its release.
Hopefully, the company will be able to fix the issue soon, so players can once against access Activision Blizzard titles.
