[rdo-users] Zuul clones failing for TripleO installation on Centos 7

Hello Folks, I tried to install the TripleO by following the instructions at : https://www.rdoproject.org/tripleo/ on my Centos machine. However, I observed that almost all the time, one of the git repos that are cloned by the Zuul is failing with a message : Failed to reach the Network. As I though this could be some network issue, I posted in Centos forum : https://forums.centos.org/viewtopic.php?f=47&t=74185 . But a deeper look into the quickstart script made me understand that the Zuul clones are the ones that are always failing. Can some one help me get this fixed as I am new to Zuul. Best Regards, Ashish Kurian
