I made one to the FBI, and then two to HHS. I made two because the first FOIA "2022-00073-FOPA-OS" Never got updated on the HHS website.
So I made one on muckrock.

It is similar to this one I found, which has gone unanswered.

I hope one day, I find out more about the time HHS ignored what I found on public FTP and HTTP servers. I still have all those letters and some info I sent them, but I will always wonder why they chose not to investigate.
