David Vonderhaar confirms details of dedicated servers for multiplayer in Black Ops 3. Check out what he said below.
Will COD finally have proper dedicated servers? – David (@Textbook_scar)
Yes, BLACK OPS 3 does have dedicated servers. There is a worldwide deployment plan for those servers. The way that the game works is a hybrid model, it’s trying to put you on a dedicated server if it’s the fastest, best situation for you.
That’s not true everywhere in the world, but it’s true in many places in the world including Australia. If it makes sense for you to be connected to a dedicated server with other people on a dedicated server than that’s what is going to happen.
