I might be missing something terribly obivous here, but I’m sort of stuck.
My apex domain is hosted on my webhoster with A and AAAA, MX, etc. records pointing to their server.
The www. subdomain is hosted using GitHub Pages.
What I did
Added a CNAME record for the www. subdomain to point to flopes89.github.io (which is the repo I want to use for pages).
Added the custom domain (www.florianpeschka.de) to that repository. This created a CNAME file in the repository, pointing to the domain
But now, when I browse to flopes89.github.io, I get redirected to www.florianpeschka.de - which then shows the contents of my webshoters server. Although the CNAME clearly points to the GitHub servers.
I did all of this yesterday, so the DNS records are properly published, an I can see that they are when I use nslookup to check the records for the domains involved.
What am I missing?
