As more and more instances are providing multiple services under the same management, we need a term to talk about this type of arrangement. A Fediverse Galaxy is a collection of federated software that is provided by the same admin or collective.
The table does not capture the fact that e.g. @stux is hosting several Mastodon instances. Should those instances hosted for others as a service be counted as part of the same galaxy?
Or would this be a Fediverse family (in analogy to Tor where relays run be the same entity are called a family).
