in my build pipeline, I query several different package hosts (npm, pypi, docker-hub etc) and Github/Gitlab. If any of them is unavailable, the build fails.

What's the best way to keep my own copy of the packages my software needs (and their dependencies), so that my build process is less fragile? Ideally, I'd only have to rely on those 3rd party platforms to download new versions or have them as a backup.

When relying on my own copy of required packages - can I expect much faster builds?
