4.21.0-0.nightly-2026-09-09-011450

Manual Override Applied

This release was manually Accepted.


Reason: Systemic hypershift-ovn-conformance HostedCluster creation timeout — create-hostedcluster step times out waiting for condition=Available. Same failure across all 5 consecutive rejected payloads (Sep 7–9). Payload contains only 2 unrelated PRs (console#17136 URL validation, csi-external-resizer#210 go dep bump). 13/14 blocking jobs passed. All upgrade paths green (5/5 micro, 1/1 minor). 4.21 nightly stream stalled 5.3 days. — https://redhat-internal.slack.com/archives/C0AMHBXQW9F/p1788958524938889
