Seems no longer happen. Will close once all linked PRs are merged.

IIRC this isn't the first time this has happened. We should probably just mirror whatever we need locally in our S3 mirror. If someone's willing to figure out how to change the build to not hit choco install but hit a custom download, I'd be more than willing to upload some artifacts!
