You should consider it, having the pool as a backup. On the other hand
that makes you reliant on outside. Ie, One could imagine some band of
crooks taking over the outside dns server, directing your pool request
to some specific machine of theirs, which they screwed up the time on,
and then ran some time sensitive stuff with your bank ( your clocks now
being 7 hours off say) .
