The Navy still runs more than a few web servers using Sharepoint, albeit behind dedicated network firewall appliances.

The Secretary of the Navy's page (at https://www.secnav.navy.mil/Pages/default.aspx) for instance, is a Sharepoint site. I used to maintain a Navy website hosted under there, and had a bunch of Hugo-specific scripts to convert a Hugo static site into something I could upload to the Sharepoint and have it mostly still work (which involved things like rewriting links and renaming files to end in .aspx).
