At these numbers, one has to start to count failover time. A "system" can be disaster tolerant but take 2 hours to recover fully, or it could also recover within a couple of seconds. It depends on architecture and available services. And in networking, you also need to consider internal and external routing update propagation times.
from where? to where? what % of the Internet is _not_ reachable from my DNS service at any given time? why is that acceptable? and more importantly, who's job is it to fix/stablize the net so these "remote" locations can reach my DNS service?
