gettting additional DNS servers geographically dispersed

Conforming with RFC2182 3.1

[ilustrate]

I currently have 2 nameservers on the same server on 2 different IP's. Does anyone know of a Service or way to get additional DNS Servers to point to my hosting IP? If possible one in Latin American and maybe a fourth in Europe or Spain...

This is the following report from a DNS stuff toolbar DNS report...

WARNING: All of your nameservers (listed at the parent nameservers) are in the same Class C (technically, /24) address space, which means that they are probably at the same physical location. Your nameservers should be at geographically dispersed locations. You should not have all of your nameservers at the same location. RFC2182 3.1 goes into more detail about secondary nameserver location.

Yes, it's possible and it will likely only cost you a few dollars a month to add your domain to back-up DNS servers.

We don't recomment specific services.

Just an afterthought: Do you also have "all your data" in one location? So, if that one location goes down then what? What if there's a local traffic bottleneck? What about dispersing your website to a number of different server centers, a la Akamai's services?

Unless your site is getting routinely hammered from across the globe my thoughts are that you probably can get by like most of us: Run your own DNS and have your host's DNS running as your secondary and tertiary DNS. That way if there's a glitch on the DNS running on your own server you've got "remote" back up. If the hosting center is "taken out" - and your files are not dispersed - DNS will not be the only issue. Make certain you have an off campus back up copy of all your data. Most competent hosts provide such a service.
