Exactly. And when you register you domain names, make sure you add both DNS servers. If one goes down, the internet know that you have a second one.
Depending on your site, should have both in different locations and on different networks. For us, we have one location and have one /24 advertised by two ISPs. If both DNS servers can not be reached, I probably have an issue not involving a DNS servers. At 02:21 PM 7/10/2002 -0500, you wrote: >Indefinitely.
