If the clients are running the standard ntpd they will continue poling
"forever" and the server can go up and down.  The clients can sync to
it when it is up and of course can't if it isn't.

BTW it helps to have more than one NTP server.  How do you know you
server is serving correct time without some kind of redundant check?
