Is there anyway that has website transfered to another hosting when current one down
I don't know which category i should post this topic. It both concerns with programming,hosting and domain as well.
Have we had any solution for a website with multi hosting? I mean how to prevent it from being down by transfering it to another host. I know that it is about A record. If my site down, i should immediately change A record point to another IP of a backup server. However, it still takes time.
Any one here have ideas of this problem?
Thank you for your reading. It must be hard to understand 'thanks to' my English.
Try to look into DNS failover services. Keeping the data in sync may be a tougher issue though. Maybe you can have a "static" version of your site in the backup location, so that the site isn't completely down, even if the functionality won't be there.
There are third party DNS Services available to allow the use of two servers or more. It won't a cheap solution though. Other considerations would also be having to have scripts to syncronise all the servers.
I would say.. use a better web hosting provider.

Once server1 (DNS1) is down, the trafic will go to server2 (DNS2)
The downtime is less than DNS expire time
I take it you never actually tried this and that you are pretty new to hosting / DNS configurations right?
When you give a set of name servers to your registrar you do realize that they are setup in a round robin fashion right?
This means that "half" of your traffic would go to server 1 and half would go to server 2 (when both are up).
When both of your name servers are up your domain would fail numerous DNS checks since nothing matches anywhere.
Also if you have one name server go down, then the other one a short time later (even if the first one goes back up) you are still guaranteeing 100% downtime.
This is not a configuration that I would recommend at all.
