So, no one knows if ntpd increases the polling interval of a server if that
particular server has a reachability of zero?

From what I can work out, from the version 3 documentation, the poll
interval is forced to minpoll if there is a total loss of connectivity and
ramps down to that if the last two polls have failed. It only goes up if
the server isn't the current system peer and the responses are valid (or
it it is the system peer and the quality measures indicate an increase).

If you have a firewall blocking returns, I think you could exceed the
sustained poll rate needed to be considered abusive.
