            Hey there and thank you for opening this pull request! 👋🏼

            We require pull request titles to follow the [Conventional Commits specification](https://www.conventionalcommits.org/en/v1.0.0/) and it looks like your proposed title needs to be adjusted.

            We are actively working to reduce the amount of code in the `equinix`
            package to avoid unintentional code sharing.

            New files should be added in an isolated package instead of adding
            more code to the `equinix` package.  You may need to refactor and/or
            temporarily duplicate existing code in order to move your new code
            to an isolated package.
