GitHub Pages on Custom Domains required github.io instead of github.com DNS
My personal homepage https://www.vorburger.ch is hosted on the GitHub Pages Content Delivery Network (CDN).
Tonight while I was having dinner, the uptime monitoring I set up for it using Cronitor.io (great product!) started firing 🚨 alerts - homepage down!
After poking around my domain registrar, DNS server and GitHub, I noticed, somewhat by chance, that I have been, since a very long time, using a CNAME of vorburger.github.com for www.vorburger.ch. This has been working since mid-2012, 12+ years!
