If it goes down for an extended period of time, as with a power loss
and the UPS ran down, then when the UPS and machine come back up say
a day or two later it will take a long time for the various DNS servers
to find it again. It's better to have someone providing secondary
name server for you. It's usually cheap. And you can configure it to
update from your name server when you change your server's data.
