[Retroactive] Actions workflow run failures after deployment gate approvals

This incident has been resolved.

On October 1, around 02:00 UTC, an isolated infrastructure failure caused GitHub Actions to lose execution state for a small number of existing workflow runs. Affected runs may remain stuck, fail deployment approvals, or return errors when cancelled. Service connectivity has recovered, but the lost state cannot be restored by retrying an approval. If you're affected, you can trigger a new run or contact GitHub Support with links to your stuck runs so we can unblock them. Once cleared, select "Re-run all jobs." This preserves the workflow run ID but starts a new attempt, rebuilds artifacts, and requires fresh deployment approvals. Before rerunning, check whether any deployment steps already completed to avoid repeating changes.
