On the little server I have running here at home, I'm now helping @internetarchive back up US Government websites and data.
You can help, too:
1. Download and run the ArchiveTeam Warrior
2. Set the selected project to "usgovernment" (or select US Government from the available projects in the web interface)
I'm running Warrior as a container with podman, but there are various other ways to run it.
