The whole of Wikipedia is backed up with 'references'. Typically news articles, scientific papers, and...blogposts. Blogposts which typically no longer exist or the domain expired, and thus the claims made in the Wikipedia entry are dubious at best. Same with certain news articles. News sites prune old articles and don't keep older articles for posterity, meaning we can't cite them anymore (yet they are still cited in Wikipedia). As for scientific papers, most of those do still exist, well, at least the free non-paywalled ones still exist. Welcome to our post-truth world.
