<pre>
    There are quite a few premerge errors that look like the following:
```
Failed to CreateArtifact: Unable to make request: ENOTFOUND If you are using self-hosted runners, please make sure your runner has access to all GitHub endpoints: https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners/about-self-hosted-runners#communication-between-self-hosted-runners-and-github
```

We should fail gracefully in these cases rather than failing the workflow. We should also probably do some investigation into why the upload step ends up failing.
