Worried about the dominance of big instances? No, really, this is quite natural.

As an emergent and self-governing system, it could be expected that the size distribution of instances roughly follows Zipf's law.

Does it?

At first you see the top 6 instances, and then the rest. But on a log-log scale the size distribution is close to a straight line, which would be expected from an emergent system.


The deviations are perhaps due to the still young age of the fediverse. Expect it to smooth out. But still, expect that the big instances will always dominate.

Data: 200 biggest instances from instances.social.



@Stoori i tend to be more worried about the tail getting cut off than it disappearing naturally

We’ve had a lot of problems with spam lately, what if, in the future, the say, ten biggest instances decided it was too much of a problem and that they’d only federate with each other? Sure technically you could still run a small instance, but with so many of the newcomers at least starting out on m.s these days, it’s possible 99% would never even think to check if you were out there

@Stoori this is obviously a more extreme example, and also something that’d be pretty shocking if it happened in the next several years

But large email servers spam filters are notoriously aggressive towards small email servers so like, it’s not completely implausible
