I just received a warning email from GitHub notifying me that I’m about to exhaust my free Actions quota. This was unexpected because I’ve been running the same uptime-monitor CI for years without issues.
The workflow runs every 5 minutes and typically completes in around 15 seconds per run. However, after checking the Actions usage metrics, I noticed something strange—while the workflow ran 1,256 times, the reported execution time is 1,258 minutes.
It seems like GitHub is rounding each run up to a full minute, even if it finishes in just a few seconds. Has anyone else noticed a change in how GitHub Actions execution time is calculated?
