I was looking at Leo XIII's encyclical on naturalism and Fɾҽҽmαsσɳɾყ,
Humanum Genus on Vatican.va, and I noticed (via
uBlock Origin plugin) it no longer uses content distribution networks (CDNs); all the content is 100% 1st party, Vatican.va (except GoogleTagManager.com…).
This is good. The site loads faster and is thus more secure.
Note: This only seems to apply to encyclicals pages. The rest of the site does load JavaScript and content from 3rd party CDNs.
