Ladder Summary
- file The module exports a single **default async function `isUp(url)`** that checks whether a given website is reachable. It extracts the hostname from the provided URL, queries the `https://isitup.org/<hostname>.json` API via `got`, throws an error if the API reports an invalid domain, and otherwise returns `true` when the site’s status code indicates it is up (and `false` when it is down).
