So we'll have discussion (centos ci infra team) about how to deal with this but at first sight, we'll just announce a date/deadline for decommissioning the old infra -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab -------------- next part -------------- A non-text attachment was scrubbed...
