If DLink were just a little bit smarter, they would have used the
stratum-2 list rather than the stratum-1 list, and in that case would have
ended up hammering on my server. I called their Irvine offices, and
eventually spoke to their corporate counsel who seems to be in "deny
everything" mode. They have no intention of doing any sort of recall of
those boxes.
DLink uses 192.152.81.0/24 at their Irvine offices, and
ntpq -n -c peers 192.152.81.100

It is unclear if either of those DLink machines are obeying the access
restrictions of the servers that they are using.
