      Description of problem

      Current production Cincinnati occasionally confuses arch-specific shards of multi-arch images as single-arch releases:

      $ while sleep 30; do PAYLOAD="$(curl -s 'https://api.openshift.com/api/upgrades_info/v1/graph?arch=amd64&channel=fast-4.15' | jq -r '.nodes[] | select(.version == "4.15.5
").payload')"; DATE="$(date --iso=s --utc)"; printf '%s\t%s\n' "${DATE}" "${PAYLOAD}"; done

^C

      Possibly triggered by a race or other buggy handling of Quay 502s while scraping releases.

      Version-Release number of selected component

      https://github.com/openshift/cincinnati/commit/ec72ca150f8537a3cfe292b8299570d86f4ffd15

      How reproducible

      Unclear.

      Steps to Reproduce

      Unclear. Possibly related to Quay 502s while scraping releases.

      Actual results

      Occasional Cincinanti shards claim the c07f... amd64 shard of the 4.15.5 multi-arch image in arch=amd64 results.

      Expected results

      Cincinnati consistently and correctly distinguishes between multi-arch images, the per-arch shards of those multi-arch images, and single-arch images.

      Additional info

      Possibly a gap since this commit that gave us the ability to handle multi-arch images?
