Scheduled GitHub Actions are now useless
Scheduled GitHub Actions are experiencing significant delays, rendering them nearly useless. A daily job is now running over 3½ hours late, while an hourly job only executes 30% of the time it is supposed to. These issues raise concerns about the reliability of GitHub's scheduling feature.
- ▪Scheduled GitHub Actions are delayed by over 3½ hours for daily jobs.

Scheduled GitHub Actions are now (in May 2026) so delayed that they are more or less useless. Here I have two graphs I collected from my work GitHub account, one from a daily job we have, and another from a job that runs hourly during office hours. Both jobs run on our own runners. The daily job is now runs more than 3½ hour late per day. And our hourly job is so delayed that it only runs 30% of the times its supposed to run! The time between when a daily job is scheduled to run and when its actually run, in minutes. How many job runs of the hourly job that is skipped each day. With this much delays the scheduling feature is now useless. What is happening at GitHub?! Victor 2026-05-19
