I have been tracking the zones with DLV records published in dlv.isc.org for
the last 34 months or so, in a sporadic way. Raw counts are below - I also
have the actual zone lists on each date if anyone wants them. Presumably
ISC have much better data.

Some of the big jumps are from when the RIPE and ARIN trust anchor
repositories were imported, extended, and eventually dropped. The
fall between 2011-05-24 and 2011-05-31 is when the *.de zones were
excluded.
