Server

A Server is an individual but identical version of Club Penguin Island designed to allow thousands of penguins to play Club Penguin without any technical problems caused by a surplus of penguins. The maximum number of penguins that can play on one server at the same time is 300 penguins. After CPIP, there were no country servers. In 2011, in one of Happy77's videos from the What's New Blog, it shows Happy77 going to another server in-game using a Box Portal. This feature was named Server Jumping. It shows an arrow pointing one way and then pointing another way like someone was teleporting from one server to another. It should be noted that the Moderator to server ratio is one Moderator for every server normally. Media 1 (Server) is the SWF database server.

Significant Servers Description
See main article, List of servers

Abominable
The most popular server around the world. The Town and Stadium of this server has the most population. This was the most popular UK server before the CPIP. It was most notable for the amount of old penguins and recordings. It is now mostly notable for "preps", cheerleaders, and football players. It is mostly populated at the Town, Plaza, Snow Forts, Stadium, Pet Shop, Forest, Cove, Ice Berg, and Ski Village, along with tons of igloos too. Most of the community advertises their parties at this server.

Adventure
Many Safe-Chat penguins are spotted here. This is the most common Safe-Chat server. Sometimes, you can't get into this server. This server is known for its enormous Safe-Chat population. You can spot many Safe-Chat Beta here.

Belly Slide
Once known for being a popular spot for bloggers, Belly Slide is now one of the most active servers due to its prominence on the list of servers, as well as one of the Mascots' favorite servers.

Deep Freeze
This was the first server ever made by the Club Penguin Team. However, it is one of the least popular servers. It was the first server on the UK section back then. It used to be very popular.

Chinook
A relatively quiet server, this quiet place is a great place to have a private chat with your best buddies, as well as the server for penguins with lagged computers, as it has a low traffic volume. Sometimes during parties flare up to 4-5 bars, but is usually quiet.

Mammoth
It used to be Club Penguin's most popular server, next to Yeti. Many famous penguins used to go on this server. It was always full and many people could never get on it, even early in the morning. Most of the people who were on that server went to the dojo. There were many snowball fights that occurred on Mammoth, but the server became overpopulated for many CP armies to log on, which caused them to change to different servers. It decreased in popularity when Zipline was added.

Mukluk
This server usually has 1 bar, but is known for having a society where members and non-members get along.

North Pole
This server used to be very popular because it was the first server in the Canada section and you would find people mostly at the dock.

South Pole
This server was popular back then because it was the first server in the Australia section.

Frozen
Frozen was originally very populated server since it used to be for "rare" and "famous" penguins, but most of the population moved to Sleet after the Music Jam 2009. When the Beta Hat Hack Outbreak occurred back in May 2010, the server suddenly got crowded. You can very rarely see "rare" penguins there nowadays.

Sleet
Main Article: Sleet 

A lot of old and beta penguins can be seen (mostly at the Dock) and lots of recordings occur here. Sometimes, penguins will ask to "share" (as in sharing passwords), but if he or she says "share," there is a possibility he/she will get kicked off the server. Loads of rare penguins and beta penguins come here all the time. You can find at least every rare item and penguin on this server. It normally has 1 or 2 bars after Zipline became the most popular server. It is strange that this server has low bars because there are loads of rare penguins there. It has started to become a busier server recently (as of at least 4/8/12), and loads of Arctic White penguins can be found there.

Private Server
This is a Private server mainly for testing, it is unavailable to the non-moderators of club penguin. There are many private servers, however many have closed due to the fact that there are no bait items on there and you can easily hack items, which was the causation of the Beta Hat Hack outbreak back in May, since that day, Club Penguin has increased their protection and security so that nothing like this could ever happen again.

Tea
Known for its enormous non-member population. It is an ultimate-safe chat server and servers around it appear to be vacant, oddly.

Winter Land
This server was significantly abundant in 2005, 2006 and 2007. This server soon started losing population when Disney bought Club Penguin. Many snowball fights are located in this server. In the present day, these servers are empty. This was the first server in population in 2006. The first ever Team Blue vs. Team Red Snow Ball fight was located in this server.

Yukon
It used to be the busiest server on Club Penguin until the Holiday Party 2010, when Zipline was added.

Yeti
It used to be the busiest server next to Yukon and Abominable until Zipline was added. It is the only server known to have the same name on 3 languages (English, French, Spanish).

Zipline
One of the most popular servers. Famous penguins such as Gary do not usually go on this server. Penguins all over the world log into this server, so it's almost always full. You are lucky if you get a chance to go on Zipline. Also, if you go on at nighttime or early in the morning there are about 2 bars so you can go on if you are awake by that time. Zipline is getting less popular at this time now.

Trivia

 * Some of the servers in club penguin have had this bug that has been around since 2005 when club penguin first opened where it would load forever.
