I set my domain name servers to point to netlify and published a netlify site which appears on a subdomain as expected. I also see the netlify record in the netlify DNS config spinner.fullmeasure.uk
However, when I add a cname record for a github pages project site as blog.fullmeasure.uk
it never appears. Using DNS tools it never gets exposed and whe nI browse I just see “not found”
I also used an alias record to see if it will appear on the apex but that has the same problem
Could I be missing something obvious? I assume it can be done as the docs indicate it should work
Thanks
