So, I'd like to propose we back up the bitflip by at least 4 hours from release time, perhaps as much as 6. I'd also like to move the update-mirrorlist cronjob back to start at :40 past the hour, so content is in place by :00. -- Matt Domsch Linux Technology Strategist, Dell Office of the CTO linux.dell.com & www.dell.com/linux _______________________________________________ Fedora-infrastructure-list mailing list Fedora-infrastructure-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-infrastructure-list
