Wikipedia is the largest wiki on the planet, with several million articles available in English and several million more in dozens of available languages.
For once, a site that recognizes the importance of third-party backups! They have a main downloads page from which you can get XML dumps from individual wikis (Wikimedia Foundation hosts more than 800 wikis: Wikipedias, Wiktionaries, Wikinews, Wikisources, Wikibooks, Wikiquotes, Wikiversities, Wikispecies, Wikimedia Commons, Wikivoyage, Wikidata).

Transferring to IA
Hydriz is currently transferring the dumps of all Wikimedia projects into the Internet Archive. Wikimedia itself has provided resources to me for transferring these dumps to the Internet Archive. Do see the collection here.
Stable, but they seriously use a lot of tactics to get donations.
