Also compare:

# with google DNS
$ traceroute singularity-hub.org
traceroute to singularity-hub.org (35.197.63.182), 64 hops max

# without
$ traceroute singularity-hub.org
traceroute to singularity-hub.org (13.72.107.243), 64 hops max

So apparently there is some registration of singularity-hub.org with a different ip address, and I'm not sure why / how that could happen.
