No, but you were talking about geo-distributed, so surely not in the
same DC, and so the remark for the need for a gbit internet
connection. The link we have is actually shared with multiple
projects, so no QoS on that and I don't know how the nfs-though-vpn IO
operations will handle that. I guess remote builders don't need really
gbit either .. people experienced with Koji should now answer :-)
