Github Pages-powered Status Website
"Upptime is a free and open-source uptime monitor and status website service. It's very different from other status-page services because it doesn't require a server — it's all powered by GitHub.
GitHub Actions is used as an uptime monitor, issues are used for incident reports and pages are used for the status website.
With Upptime, you'll get a staticly-generated status website showing users your websites' live status, incident history, and response time graphs. The website is always up-to-date as it uses the GitHub API to fetch data in real-time, and is built using Svelte and Sapper."
