I came across a thread earlier that was asking others about this, and I shared how it came about for this instance, and decided that it would be a good dedicated post here in general just in case anyone is curious:

I started a habit a while back ago of naming any servers I run based off of names from Greek mythology - my primary server is Zeus but most forms of just “Zeus” in domain form are already taken. Similarly, I call the quasi-internal network that this server runs (since it’s a hypervisor) “ZeusNet”…

Problem with that name is “ZeusNet.net” is redundant and would irk me, I wanted something that still ends with the .net TLD (though my personal domain ends with .network).

Thus, zeuslink.net is what I came up with given that “link” can mean “network” and the combination isn’t as redundant as “…net.net”!

Funnily enough, originally my instance was originally under the colony subdomain which I quite liked… But unfortunately I didn’t set things up properly due to how I have everything else setup, and I had already dipped just enough in the federation that when I reset everything so that it actually worked properly, the keys that my server identified with no longer matched which broke my ability to federate properly. Which then forced me to reset everything again under a completely different subdomain (I’m glad it was on a subdomain instead of the root domain for that reason) since Lemmy doesn’t have a “self destruct” option like Mastodon has (which tells all connected instances “Hey, I’m going down - forget you knew me” as far as I understand it).

And that, is the story of how we ended up with the name “[The] Outpost” on the domain zeuslink.net!
