Looking in delorean logs, the cause is:
DEBUG: https://buildlogs.centos.org/centos/7/cloud/x86_64/openstack-pike/repodata/repomd.xml: [Errno 14] curl#7 - "Failed to connect to 2607:1680:0:1::2: Network is unreachable"
This should be resolved, buildlogs. centos. org is now accessed via caching proxy in openstack-infra.
