CI Failure Analysis

ARC assessed the following failed CI jobs via AI skill assistance:

e2e-aws-ovn-builds

• Category: Infrastructure Flake ---
• Summary: The openshift-e2e-test step failed because the [sig-builds] test could not pull the centos:latest base image from any registry — CentOS is EOL'd and the image no longer exists anywhere. The cluster provisioned successfully; the builder PR code was never actually exercised. ---
• Failed step: - **Step name:** openshift-e2e-test- **Phase:**test- **Step script:**ci-operator/step-registry/openshift/e2e/test/openshift-e2e-test-commands.sh ---

Retesting infrastructure flake jobs:
/test e2e-aws-ovn-builds

Note: Required status of Prow CI jobs was determined based on this repository and branch's Prow configuration and GitHub branch protection settings as of 2026-07-31, when this PR was first detected. Only required CI failures are assessed.

CI Failure Analysis

ARC assessed the following failed CI jobs via AI skill assistance:

e2e-aws-ovn-builds

• Category: Code Issue (test fixture uses an EOL base image — unrelated to this PR) ---
• Summary: The e2e test failed because the test fixture Dockerfile uses FROM centos (CentOS Linux EOL), and centos:latest is no longer available from any registry. This failure is unrelated to the PR changes (a gRPC vendor dependency bump). ---
• Failed step: - **Step name:** openshift-e2e-test- **Phase:** test - **Step script:**ci-operator/step-registry/openshift/e2e/test/openshift-e2e-test-commands.sh- **Pod:**e2e-aws-ovn-builds-openshift-e2e-test(namespaceci-op-x4g8gry8) - **Duration:** 50m37s before failure (exit code 1) ---

The following CI job(s) failed due to issues in this PR's changes, not CI infrastructure:

• e2e-aws-ovn-builds

Please investigate and fix the above failures.
