Global CDN uses Cloudflare, a service that stores and delivers files, to load gtm.js and gtag.js from a server closer to the visitor. This helps these files load faster for people in different regions.
If you want gtm.js and gtag.js scripts to load from a location close to each visitor, Global CDN gives you that in your server container dashboard. You keep all your setup in one place and do not need a separate CDN service.
