If yes what servers are available and like how many active players?

In terms of d2jsp, Not too many active players. In terms of just the game itself, Reboot is the most active players, especially during this time (Summer) due to the many events, including newest updates.

Bera I believe would be the most populated non-reboot server; still many actives, but not as full as reboot.

yeah, the game is bigger than ever. (mostly korea though)
