Brazillian here. Out biggest Mastodon instance (ursal.zone) is locally hosted, but is behind Cloudflare and appears as US in this list. Most of Brazilian instances are foreign hosted because of cost. This table means nothing in terms of fediverse penetration on Brazil. We have a huge population, and even as most of Brazilian are monolingual, the minority of bilinguals are millions that can read English. Even monolinguals are doing just fine using Brazilian instances, even if foreign hosted.
