You should anyway to spread the load.

I would like to put my 2c here. Fediverse, defederated and self-hostable platforms give you the opportunity to not be closed within a walled garden. I would say that people on the fediverse should be more flexible and be ready to change an instance, or self-host themselves if that is their thing, in case something goes wrong. You must remember that it is you now who decides where to build the tent. I think of it as a summer camping holiday: You go to a camp, stay there for a few days, but when it starts to rain in the area, becomes boring, or a group of noisy campers comes in, you relocate to another camp, if you cannot do anything about the problem in your current camp.

So, I would say you as a fediverse user should be prepared to rebuild your tent repeatedly, even if you stay on a single instance for a long time.
