Server

Servers are worlds in Club Penguin that house a certain number of penguins. Each server has a maximum limit, 300 penguins.

Asterisk * means that the server is Ultimate Safe Chat Only (penguins can only choose from a number of ready messages. However, there is a way to get through the block, see Glitches).

Server Selection
Server Selection was added to Club Penguin on July 16, 2008. It shows penguins their top recommended servers. The first server listed the server that was last used by the penguin on that computer. The rest may be, recently used servers or servers with buddies logged on.

Members get more room on a server where as Non-members get less room.

Population Bars
The population of a server is indicated by 1-5 green bars. The definition of the bars are statistically explained here:
 * 1 Bar: 0-60 penguins (Least populated. Not recommended unless having a extremely low speed connection)
 * 2 Bars: 60-120 penguins (Not recommended unless having a low speed connection.)
 * 3 Bars: 120-180 penguins (Moderately recommended.)
 * 4 Bars: 180-240 penguins (Perfect.)
 * 5 Bars: 240-360 penguins (Moderately recommended, unless in a party.)
 * Full: 360 penguins (Refresh page till it is available.)

To browse through other servers, players should click on the message that says "More Servers Click Here" (located on the bottom right corner) to choose from the other servers.

Trivia

 * Without the 360 penguins per server limit, it would be possible to have 3400 penguins online at the same time (when the Migrator is docked) or 3100 at a party or 3000 at any time. Per server.
