I just went to the Survivor Challenge website and they have up this message:
Survivor Challenge Closed
Unfortunately, we will not be running a Challenge for Survivor Pearl Islands. This game has become much more popular than we expected, and our current servers are not able to properly manage the load, and at the time we do not have the money to move to new servers. We will be looking into alternatives and there is a chance that we will be back in the future, but for now, you will have to find an alternative. Thank you to all who have played in previous seasons. It has been fun.
So, there is no challenge this season but please come join us for Media Whore and Scurvy Dog...Mama
