We are in the process of transferring the hosting and maintenance responsibilities of the wiki from Chucklefish to ConcernedApe, which is why the wiki will temporarily be hosted at stardewcommunitywiki.com.

Prior to the transfer to ConcernedApe we will update this site with the date on which the transfer will occur.
