After some issues with my last host I migrated everything to Hostdime.com.. I now have my DNS ns1.webaccelerate.net & ns2.webaccelerate.net pointing there... Is it possible (and would it help) to set up a second reseller account with another company, and create ns3.webaccelerate.net, & ns4.webaccelerate.net pointing there.. then duplicate everything at hostdime on the "new" machines. If by some act of God Hostdime went down, would the other nser's pick up? Thoughts??? Thanks guys. "J"

If you have to do that, then you probably should be with HD in the first place.

Kind of. The nameservers are polled in the "last responded" order, meaning that if ns1 responds first to queries, that gets the result. Next time a lookup occurs, if ns1 is slow, and ns4 responds sooner, that one gets the nod. The way to get this to work, although not automatically, would be to set up all 4 nameservers, but point them all to the same IP/account. If one account goes down, switch the remaining one to itself. Downside? Not automated, dynamic data (databases, etc.) will not be in 'sync' and a few possible mail issues. May be other issues as well.

I think it would be cheap enough to just pick up another domain instead of going through the trouble that would probably occur. Eric

geting another domain won't achieve what he is trying to do! i think he want a backup host account that will kick in if his main site is down!

Oh yes, my mistake for sure. Sorry about that. Eric

I think he has to do it this way: ns1 - Hostdime ns2 - Other Host ns3 - Other Host ns4 - Hostdime For mail issues, he can go for seperate server and make the respective entry. For Database, that he can hard code the IP. It would be really difficult to syncronize two databases, especially in a case if he is going to have forums. Regards, Harsha

The best solution you could probably have would be an offsite DNS (another server) that you could switch quickly for your domain name might help as to what you're trying to achieve

Thank you everyone! Harsha.. I think you hit it! I'm still confused on the mail issue. But IPing the Database.. "beauty". Bear... Dude.. er.. ya lost me. :-) But it sounded great! Kardyss... I was chatting with "Dimelive" via AIM at 2am this morning. 90% of the time if I have a question and call.. Tech support answers the phone. Maybe coming from EISHost it doesn't take alot to make me happy... but I am. :-)

Sorry. It's pretty simple, really. When a request is sent for name to IP translation (lookup), it will ask all nameservers listed with the domain (ns1, ns2, ns3, ns4), usually giving priority to the one that responded fastest on the last lookup. If that one is slow, the first one to respond with the information is the one used, and the first one "asked" the next time. It does *not* follow numerical order (although it might, just by chance), as in ns1 first, then 2, etc. What does this mean? If ns1+2 point to one server, and ns3+4 to another, visitors might get either server, depending on which one responded first. What I suggested was to set up the 2 servers with different nameservers (ns1,2 on one, ns3,4 on the other), but tell both servers (through WHM) to send browsers to the IP for the "main" server. This way, no matter which server's nameserver responds first, it gives them the right server. If that box dies, you can use WHM on the working box to point to itself (it's own IP). Unfortunately, once the dead box comes back, you now have the first issue again, with either box answering, at random.

there must be a proper way to do this. sound like a basic requirment for a critical website!
