FYI over the next day and a half we will be repairing the survival map, it has been hosted for 1 year now and has gone through many updates. When we run dev builds of plugins and Bukkit issues happen every time the minecraft server gets updated (1.0 - 1.5). So, now we are fixing it, and to put you at ease: it will only be down for a short while and afterwards we should be good for a long time.
So, for the next day or so the creative map will be the only map that you have access to. Again this will only be for a short duration, and after that point in time the server will resume as normal.
We thank you for your understanding and patience
