GitHub stopped updating its status page with aggregate uptime numbers some time ago — if you use it regularly, you might have a feeling why. This is the missing version.

We rebuild platform‑wide and per‑service uptime from archived status updates, derive minute‑level downtime windows, and map incidents to services whenever the source data allows. Everything is open source, and PRs are very welcome!
