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.
And it will take me all of 60 seconds to turn off cloudflare on my instance I I ever have to and 5 min for TTL on the DNS to expire, bit in saying that I have moved from a small indipendent VPS to a much larger provider for cost saving (Mostly for storage, but also double the core count).
