Just stood up my first synapse server. Everything working as expected
(all in docker). When I look at the synapse docker logs, it's pretty
constant. Repeating over and over patterns like this:

I'm guessing, these are from homeservers where sombody had joined a
public room that I've now joined, and my synapse instance is trying to
connect to them all to get message history?

Am I close to right? Any way to not just constantly try them over and
over?
