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. Matt [cid:5ECC30BA-3FDF-4B27-B657-714849412377]
