For quite a while my VPS was misconfigured – any HTTP requests it got but couldn’t assign to a vhost, it redirected to the main website, avris.it. I didn’t think it would be a big deal, until I recently found out that my post Ungoogling is indexed by Google under https://askara.avris.it/blog/ungoogling
This subdomain hadn’t existed for a long time already, my server doesn’t serve a certificate for it anymore, but it requires HSTS, so browsers end up showing users a scary error message.
I had to do something about it.
