Server list

Minecraft classic

Mojang currently only provides a server list for the free (classic) version of minecraft which can be found here: http://www.minecraft.net/classic/list.

Minecraft for premium members

As mentioned above, premium members (http://www.minecraft.net/game) do not have a server list directly available from the game itself or on the official minecraft website (minecraft.net).

Therefore, additional websites dedicated to listing minecraft servers exist.

Several server lists: http://serverlistminecraft.com

http://servers.wipaz.com

http://mcserverstatus.com

http://minelist.net

http://mymcstatus.net

http://list.mcmyadmin.com

http://mcserverlist.net

http://minecraft-server-list.com

The downloadable version of minecraft does support adding your favorite servers in the Multiplayer section. It allows you to see if a server is online, how many slots it has and how good your connection (ping) to it is. This feature was added in version 1.8. The current appearance of the server list can be seen in the picture.

Trivia

 * Hovering over the connection status icon will tell you the connection speed to the server.
