While this is good advice, I think it is also important to
consider your customer base. I could easily host an authoritative
nameserver for my domains in Japan, but I elected not to do so,
because most of the end users who would be querying it are in
Canada, and, with one nameserver in Canada and one in Japan,
they would get a long RTT on DNS queries roughly half the time.
