I'm noticing a much smaller list of communities here
(self.support)
You can ask questions about the Lemmy.nz instance here.
This community also serves as our Meta community, with posts about updates to the Lemmy software on Lemmy.nz or other things relevant to Lemmy.nz users and not relevant to other instances.
I feel like as lemmy matures, this is a process that a client app can automate. eg. If given a lemmy community url check if it exists, if it does then search for it on the users intance, then retry periodically until it's available.
