User blog comment:Brandon Rhea/Wiki domains will be changing from wikia.com to fandom.com in early 2019/@comment-35687627-20180816221852/@comment-34106721-20180816231249

it won't effect how FANDOM itself runs, no. it's just a URL change. the main issue that myself and most people have are for non-fandom wikis having the "fandom.com" url attached to it.
