As you may be aware by now, the technology which Club Penguin Rewritten is currently reliant on (Flash) will be retired by browsers at the end of this year. In order to ensure that the game continue, the team have been working on a HTML5 version, which is a more modern technology that will be supported long into the future, and you can learn more about it here!
Part of the transition between the two different types of technology will require some downtime at the end of the year. In other words: from December 31st, the game will be down for “several days”.
There are only 7 days left of the Adobe Flash version of Club Penguin Rewritten, and the game will be down for several days starting on [December] 31st, which is when we will complete our move to HTML5.-Thorn, Club Penguin Rewritten administrator
This is important if you enjoy Club Penguin Rewritten, so please be aware that there is only one week left to enjoy the current “version” of the game before it’s retired.
