The first KSK was introduced in 2010.  That statement is about doing 
a KSK after five years.  I multiplied the duration by two, hence the year 2020.

There was a discussion about the rollover in 2013.  The delays since 
them could be interpreted as meaning that the KSK roll is 
indefinitely postponed.  At some point there may be discussions about 
whether all this is reliable.

The numbers are from

According to data published by APNIC, 10.82% of DNSSEC validation 
worldwide is from Google Public DNS.  It should be possible to take 
that number out of the equation by talking with someone at Google.

The (8%) number is not meaningful if I cannot explain it in an easily 
understandable manner.   Would breaking resolution have an impact 
which is similar to the 2016 Dyn outage?  Would it take down a 
significant part of the internet in a country?
