Well I’d say most of them are federated together, or at least those with a good amount of users. In practice you don’t really get islands other than I guess troll instances that everyone has blocked.
And AFAIK as long as an instance isn’t blocked by yours (and vice versa to be useful), you can follow a person on that unfederated instance and it should just work and get federated.
Are instances federated or rag-tag islands?
islands can be good (for unpopular/generally hated content)
I’m sorry that whoever down voted you didn’t see what you were doing.

Any instance that interacts with any other instance is federated. Which is the vast majority of instances with more than a handful of users.
