I'm only receiving NS queries for "." from spoofed 66.230.128.15 and
66.230.160.1 via above.net (of my three transit providers) and none from
peering.  This usually indicates a single source, such as one rooted machine
on non-BCP38 net spewing most of a gigabit.

Have you had any luck tracking back the source of the spoofed packets?    If
me talking to above.net sounds useful, let me know.
