Are there any currently executing NTP surveys, like Guyton's (1994),
Minar's (1999), Mura/Torres (2005)?
My public NTP servers sometimes have not-so-public (but still accessible
to the wide world) stratum 1's peering with them, and I'm honestly
surprised that only once or twice a year does someone traipse the
ntpq -c peers or ntpdc -c monlist references and end up querying
the not-so-public ones.
I've done some surveys of my own and counted 640000 mentioned machines,
but I suspect I'm only scratching the surface because so few servers
respond usefully to ntpq -c peers or ntpdc -c monlist
