Interval cron trigger not triggering as often as expected

Describe the bug I have an action that should be running every 5 minutes, which is the maximum amount of times an hour according to docs. Therefore, there should be 12 events per hour in an ideal run. I am getting 2–4 events per hour.

Unclear if this is an issue with the frequency or with an interval cron setting as a whole. Actions at a defined time (ie - cron: '0 7 * * *') work perfectly in the same repo.

To Reproduce

on:
  schedule:
    - cron: '*/5 * * * *'

Expected behavior Action is triggered roughly every 5 min.

According to https://docs.github.com/en/actions/reference/events-that-trigger-workflows#scheduled-events

Note: The schedule event can be delayed during periods of high loads of GitHub Actions workflow runs. High load times include the start of every hour. To decrease the chance of delay, schedule your workflow to run at a different time of the hour.

Also, the schedule run might get delayed if the actions service is under DDOS attack. 😞

I am going to close this since the schedule is controlled by the service, if you have lots of missing runs for schedules, please reopen this with some sample data (repo URL + time interval), I can help you check our telemetry.

The exactly same problem here as well 😦
