Selecting a site outside of your control is valuable. When I was hostmaster@cic.net, we "traded" with mr.net. These days, if I were in the same role, I would want to have three instead of two. Asia, Europe and US someplace. If US only, east, west and central.

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. -Phil
