A search of the past 14 days of CI runs for the string "package_availability" reports "27 runs, 89% failed, 17% of failures match": https://search.apps.build01.ci.devcluster.openshift.com/?search=package_availability&maxAge=336h&context=1&type=bug%2Bjunit&name=&maxMatches=5&maxBytes=20971520&groupBy=job

The failures all appear to be caused by a dependency resolution failure for the "bind" package.
