The video inspired me to explore the open source grid map at atlas.eia.gov, but it sure looks like the online map was locked down.

Despite the sidebar saying the map is visible to the public, the maps never load and I'm seeing access denied errors for map resources in the console.

There could be multiple explanations for the map to stop loading, but the error messages sure give me the impression that it was to restrict access to this information, and that makes me a little sad even though I can understand why it might be tempting to restrict given the circumstances.
