From a purely practical standpoint, the preview server isn't designed to actually be used by Wikia users, the actual Wikia servers have a lot more resources to deal with everyone - they are servers that are available so that staff can test new updates they're planning to make.

There isn't a fix for this, as far as I'm aware - apart from asking people not to use the preview server.
