[Rdo-list] Odd networking behavior with fedora mirrors

Folks, Occasionally during Kolla's gating builds of RDO, we have the following errors: http://logs.openstack.org/13/198213/7/check/check-kolla-functional-f21/87... This use if IPv6 seems new – I don’t recall it being used prior. It appears it is not without bugs. Could someone have a look or send to the appropriate people? Thanks -steve
