I would have thought the WAN's additional delay,
and increased jitter (as compared to the LAN)
would have mattered more in the cluster algorithm,
causing the internet servers to be tagged as outliers,
if they were not close enough to make it into the cluster.
Was the dispersion from the LAN servers higher than the
internet servers, due to auto increasing poll times?
