Do let us ( https://pagure.io/fedora-infrastructure ) know if you are still seeing capacity issues with s390x. In mid december: * We had mainframe folks tune things to give us more priority * They added resources so we could add 7 new builders. * I moved all the ci jobs to a seperate channel so they only used a subset of builders instead of hogging all of them. Since then, I have not heard of any particular issues with them. I guess we will see next week for the mass rebuild how it does. kevin
