Hope this is the right place to report this, as this community is mentioned on the contact page of join-lemmy.org.
If you go to https://join-lemmy.org and click on ‘run a server’, this results in a 404. This is a shame as it puts up a roadblock for those wanting to create their own Lemmy instances.
yha, it’s been that way for over a month for me, lots of broken old stuff.
