Well, of course it isn't going to be on Fandom if Fandom closed the wiki. However, they may have moved to a different host. The wiki I linked to definitely seems to be a former Fandom wiki since it has a bunch of extraneous pages associated with Fandom's old threaded discussions features.
Edit: Based on viewing page histories and this Miraheze task, I am convinced that the wiki I linked to is definitely a former Fandom wiki about CountryHumans. Whether or not it is the one you were using, I cannot say since you never gave any details besides the name.
Edit2: I have done some more digging. The database dumps currently at this URL appear to be from an October 4, 2021 attempted recreation of the wiki by Benramos1030. The database dumps provided in the Miraheze task I linked to appear to be the "original" wiki with the latest revision having been made on August 11, 2021 at 3:05 PM UTC.
