The author examined the distribution of instances in the fediverse. Given that many instances are hidden behind CDNs like Cloudflare or Fastly, the author employed ActivityPub’s functionality to discover the actual hosting locations of servers. More than half (51%) of the fediverse is hosted within a single hosting company. The author suggests that the fediverse hosted mostly with a few major providers, deviates from its initial objectives.
Just by looking at the biggest instances someone could think that they cover most of the users but I’m positively shocked.
Kudos for the work!
But the summary is missleading.
