Pipelines , Workflow Creation Errors and Missing GitHub Status Updates
Final update
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.
