[cobalt-developers] About DNS service

[Pablo Ibarrolaza <pablo@xxxxxxxxxxxxxxxxx>]

I read this advice From: Jeremy Anthony Kinsey <webmaster@xxxxxxx> in old 
message in the list-users:

"Just a few key things to keep in mind when hosting your site somewhere,
whether it by dedicated or shared hosting:
1. If you intend to host a site on the internet at someone elses
facility make sure you have a backup of your site!
2. If your business is mission critical and it is imperative that your
site be up, ie., you business depends on your site, then host your site
at more than one provider and use DNS to create redundancy.
3. Make sure you have a backup of your site!
4. Consider colocation of your own box at someones facility if you do
not want someone inadvertently wiping the box clean.
5. Make sure you have a backup of your site!"

I agree and I looking forward for a DNS service Indepent of the servers.
I try to do this:
I living and working in Argentina and my hosting is in USA.
I've installed Linux in my desktop with rysinc client I have a DSL 
connection and I try to conect my desktop with the RAQ4 and mirroring 
complete box (/home and /var really) I think I can do this without problems!

But now I need a DNS Service Indepent of my RAQ4 in USA or my Desktop in 
Argentina. With this DNS I like to run my sites on RAQ4 if RAQ4 crash I 
could change my DNS to my Destkop and run my sites from it.
This is the idea.

Could you give me and advice searching a good and RELIABLE DNS service.

Thanks! in advance and sorry my english is poor.
