This server is called hakodate.catolic.de.
Hakodate is a southern coastal town on Hokkaido, the northernmost Japanese main island.
This server replaces a server named Sapporo, which is the capital of Hokkaido.
Okay, but why is that a server name?
Sapporo was originally set up one December. I like snow. Hokkaido is renowned for snow, and Sapporo celebrates Snow Festival.
Hakodate is close enough to it to still represent The North.
I have traditionally used locations, fictional or real, as host names.
I wanted a domain name that didn't contain my name or referenced a game I had been playing many years ago.
The chosen one is one letter off a world religion and a tongue-in-cheek promotion of cat worship.
