One could try to access a different public ntp server. Sometimes a different 
ntp server will solve connection problems.

Very stale article.

I don't think they can without a LOT of work and expense.  The 
problem is messy - network reliability (mostly at your end) vs ntp 
server overload (at their end).

In general, one tries to be "polite" when accessing expensive 
services such as atomic clocks.  That's what the minpoll 12 maxpoll 
17 settings do.  In some cases, the polite queries don't get thru. 
At that point you have two choices:  wait a while and keep at it, or 
hammer your way in to the server.  Adding iburst tells the daemon to 
hammer its way in with a bunch of queries, hoping that at least one 
gets thru.  If everyone did that, the server (and its network 
connectivity) would be crushed under a pseudo- denial of service 
attack.

It's not that important, and your Mac already has a built-in clock. 
This sync is simply to correct the drift now and then.
