True, but 2ms latency in syncing a backup system is much better than 1
month complete loss of service due to *poor* continuity planning. We
all know what the next big threats are (nuclear and/or biological), is
it worth the risk that the next (and there will be) event is small
enough not to affect an area 65 miles across?
