I get this comment sometimes and also other comments saying it 404s. The site has been up for years but seems there's still some old DNS floating around. Or some misconfiguration on my side.

This is due to one of your AAAA records: ::ffff:157.245.83.16. (The other one is fine.)

CLI:

    dig aaaa saile.it
    curl -v --resolve "saile.it:443:[2a04:4e42:2::775]" "https://saile.it/1145-pull-requests-per-day/"
    curl -v --resolve "saile.it:443:[::ffff:157.245.83.16]" "https://saile.it/1145-pull-requests-per-day/"

GUI:

It will if your certs are managed via a git repo.

... but a small PR might warn you when your renewal automation breaks, before the cert actually expires: https://heiioncall.com/blog/barebone-scripts-to-check-ssl-ce... (a small blog post I wrote with example scripts for checking SSL cert expiry from Bash, Python, Ruby, more) ;)
