for authoritatuve servers, i try to have one on a very different
backbone on a distant continent. i make deals with friends. there have
been just too many failures where servers were in the same facility, or
behind the same routing, or on a single backbone. see rfc 2182.
for customer- and infrastructure-facing caches, i try for as different
routing domains and peering/x-stream exits as i can while keeping them
easily reachable by their clients.
