[Matrix] Are there different Matrices? If so, how many?

The Animatrix appears to show a few different simulated universes, such as the techno-noir one and the more suburban one with the "haunted" house. Are these totally different "servers", or just different parts of one huge Matrix?

They are previous versions of the Matrix which humanity rejected. Later, the Oracle discovered that humans needed a choice in order to accept the Matrix, and thus its current inception of a modern society which people were able to be unplugged from it was born. Programs such as the twins and the "werewolves" in the Merovingian's employ are said to be programs which came from these previous versions of the Matrix.
