My 06:30 cron has never once started at 06:30

A developer found GitHub Actions cron jobs can start hours late or fail to run at all.

A five-minute schedule ran only about 5% of the expected times, and a daily job was delayed by 1.5 to nearly 4 hours.

They also observed GitHub silently disabling a scheduled workflow after inactivity.

In response, they built Cronwake, a read-only GitHub App that monitors scheduled workflows and alerts on late, missing, or disabled runs.
