Backup DNS
Hello experts,
I have a client running an online shop website. Since many times his current website hosting server was down he wants to move a new hosting provider.
He asked me if its possible to run the site on 2 different hosting providers meaning that I will set the domain to chance two DNS from the 2 hosting.
So when one server is down the second DNS will serve as a backup. Is that possible? And how? I remember trying it once but it end up with as a mismatch.
If anyone can guide me or have a better solution&. Please. Thanks

Your client's website must have been registered in their ISP's DNS servers already with an ipaddress of existing web hosting server. If you want to host this website to one more web server, you can contact your ISP to add ipaddress of the new hosting server to the existing HOST A record that they have.
If you're hosting your own Microsoft DNS server for public namespace, follow these steps:-
1) go to the zone by the name of your website eg. abc.com
2) right click on ABC.com zone and select add new HOST A
3) Don't specify any name to the HOST A and simply give the ipaddress of the new web server . By not giving any name, it will create a "same as parent folder" HOST A record in DNS which will again resolve to your website's name and we should be good to go.

hello lavionline,
this both are shared hosting services. what i mean is the client pay for 1 hosting company already but since their server is down so often he would like to pay a second hosting company and upload the files so he can have a backup. i can deal with the domain DNS and put a 3rd and 4rth DNS that's not the problem. we talk about os commerce based shop with mysql database. my question here is if i add the DNS's what happens? which site will serve as the main and which one will be used for backup. i tried it before but i saw that it causes problems. thanks!

Hello Plod, thank you for this but it's a bit too much technical for me. Can you explain this in simple words so i can understand and you bottom line ... can it be done simply?

An online shop will almost certainly require session affinity so you would need to use a decent load balancing method such as a hardware load balancer or MS NLB worst case. This requires physical proximity for the two web servers which you won't have in this instance.
