When attempting servicing, it fails with error similar to: Failed to prepare node 60b0997a-e942-43c3-868c-5a3b3c3c4088 for service: Validation of image href http://metal3-image-customization-service.openshift-machine-api.svc.cluster.local/2b5d92b1-0f03-4958-a382-f15228250918 failed. The issue often happens in two-worker clusters when one worker is taken offline for servicing. Similar has been observed in three-worker cluster with two taken offline for servicing.

The issue has been diagnosed in depth in https://issues.redhat.com/browse/OCPBUGS-48789 however the part that remains to be solved is enabling BMO to keep retrying servicing if this issue is encountered, so that once ICC connectivity is restored the operation may continue
