A similar problem would be created if a web server relied on DNS that was only hosted on servers in New Orleans.
Do you (or somebody) know of recent numbers of what percentage of domains have all their DNS servers in;
a) same subnet b) same AS c) same geographical "zone" (faultline, floodplain, coastline, etc.)Obviously if everything served by the DNS is co-located in the same failed facility, it does not matter that much if the names resolve to IP addresses which are unreachable anyway.
