When ICANN rolled over the KSK for the first time in October 2018 things apparently went smoothly with only a few minor incidents reported, but after a while it became evident that some resolvers did not like the rollover. This can be measured by looking at the DNSKEY queries from those resolvers which in some cases have increased by 100x at F-root. Some of those resolvers in this process expose a number of interesting behavioral patterns. In some cases this may expose the query frequency and in others the upstream selection algorithm.
We will explain the patterns using data collected by a subset of F-root instances around the world and look at geographical differences. In some cases this may expose the query frequency and in others the upstream selection algorithm.
