This has nothing to do with cPanel. What you need is to have PI ip adresses and set up a BGP router where the two different provider's lines connect to. You'll have to work this out with both of your providers to set it up correctly.

Otherwise, if you try the cheap version, you'll end up with different IP numbers when one of the lines are down, which will in turn make all your servers stop responding.

Not really I'm afraid. Since all the servers are working off on static IP adresses and all your customers domain names as well, you need to keep the same IP address - which leads you to the BGP router and your own Provider Independet ip-adresses.

I Was Able To Use 2 Static IPs From My 1 ISP By Useing This Setup, You Could Try The Same

1 Way Is Haveing 2 Network Interface Cards And Using The IP's From Both Cards
Or What I Do

**USE THIS METHOD AT OWN RISK**

Go Straight From The Modem Into A Hub/Switch NOT A Router Giving Off 192.168.x.x
So You Would Be Recieveing 2 WAN IP's Straight To Your Server

And If You Want A LAN Setup You Would Then Just Plug The Router Off The Switch

Hope That Helps

That's fine for your own computer, but when it comes to DNS, apache and so on..
It's just the same as if you suddenly would switch your cPanel server's IP number all of a sudden. All the DNS records will still point to the old IP number until you change it, and then you still have to consider the visitors ISP's TTL for your domains. I would say a downtime ranging from 0-48 hours at least. (and thats after you chance the IP in the zonefiles and dns server).
