I see the revoked KSK-2010 has gone from the root servers on schedule

It should be interesting to see whether the DNSKEY query rate to the
root servers (1) increases even more (2) falls off now (3) stays much
the same. That might give us a whole 1.58 bits of clue as to the cause
of the increase in the first place... :-)

The root zone without KSK-2010 went out ~1440 UTC. We've already seen a massive drop in DNSKEY queries from everywhere we have data. Note the graph below.
