[grumple]

We ran into intermittent failure with Github download urls around a month or two ago that caused our builds to fail (there was no github status, but we replicated the failure easily manually). In response to the failure, we started self-hosting the dependency.

The fewer external dependencies you depend on at the actual point of builds/deploys, the better. Since you're using a fixed version of the dependency anyway, you might as well self-host or include it in the ami or container.
