I was thinking that the ntp.org servers on any particular network are a small
set of exceptions to a general rule to rate limit outgoing NTP traffic.
www.pool.ntp.org allows any NTP operator to opt-in to receive NTP traffic
should their clock be available and accurate.
I believe you, but I don't believe that the set of ntp.org servers changes
so rapidly that it is beyond the ability of network operators to handle
the ones on their own networks as a special case.
