    On March 18, 2026, customers using workflows configured with serial groups or terminal job dependencies experienced two brief periods of disruption due to a code change. Between approximately 12:08 and 12:35 UTC, affected pipelines encountered errors when creating workflows. For pipelines created in a second window from approximately 14:23 to 14:35 UTC, GitHub status updates were not delivered for some completed jobs. Long-running workflows triggered during this window may encounter these errors after the resolution time. The underlying change was reverted in both cases. All systems have been operating normally since 14:35 UTC.
