Since long time ago, I host my website on my own server. As time goes by, the maintaining cost for this website appears to increase indefinitely with complexity from Podman, Ansible, Buildbot and so on. I have once tried use GitLab pages to host my website. However, it does not support adding custom HSTS headers, so I need to opt-out HSTS preloading if I don't want to see a warning on hstspreload.org.
Opting-out HSTS preloading is as simple as opting-in.
I just changed the
Strict-Transport-Security header for my server and submit a request at hstspreload.org.
As it is said that the removal can take a long time, I'm curious how long it will.
So, here is the timeline.
