Activities behind for publishing to an old hostname for my instance before production ready

Question for everyone…

Recently I got GeekRoom.Tech fully operational and federating properly. However, before full success, I ran into a lot of issues and at one point had the domain as www.GeekRoom.Tech.

As you can see (here)[https://grafana.lem.rocks/d/edf3gjrxxnocgd/federation-health-activities-behind?orgId=1&var-instance=All&var-remote_instance=geekroom.tech&var-remote_instance=www.geekroom.tech&var-remote_software=All] the www version of the instance still has a bunch of instances trying to publish to it.

What is the best way to resolve that? I assume that those instances are actively trying to push activities but are constantly failing, potentially eating up bandwidth for them.
