So, from 3-jan-2022 i see two jobs failed with mirror issues:

Two timeouts pulling from mirror.centos.org to different repos and also some jobs passed between those so I'd say it's a infra issue, not config or job issue.

I see that in the same jobs some packages were installed from repos ci infra mirrors so i guess the problem was specific to mirror.centos.org. Something that could improve this is to move centos repos configs from mirror.centos.org to use mirrorlist to identify closer mirrors. IIRC, jobs in oooq use the configs coming from DLRN repo?, i need to check. Other option would be to use the opendev mirrors but that would be oooq specific and some logic from tripleo-ci would need to be implemented to modify the mock config on the fly.
