 This transport plugin uses standard [`fetch()`](https://developer.mozilla.org/en-US/docs/Web/API/fetch) to retrieve remote content from alternative endpoints — that is, HTTPS endpoints that are not in the original domain. This enables retrieving content even if the website on the original domain is down for whatever reason. The list of alternative endpoints is configured via LibResilient config file, `config.json`.
