We don't host user content under the gitbook.com, or at least we've stopped doing it a few years ago.

User content is stored under *.gitbook.io, similar to GitHub.

Google blocked all domains that contained "gitbook" in our account, even ones that are used for some infrastructure and are not accessible by the public. We don't know the exact reason for this, maybe they've blocked gitbook.com because we still have some redirect for content that was hosted under it years ago.

And yes we are going to make changes to host our status page under another domain.
