I think we all learned a lesson after the Afrihost disaster the past two weeks. People lost thousands a day by just taking their website offline.

Any suggestion on how to guarantee 100% update on a domain? (I'm not a expert and still learning, so no big words please).

Idea
Is it possible to split a mirror image of your website on a different provider, change the third and forth nameservers at .co.za with the second host, so if the first one goes down that it automatically go to the second provider - meaning that your backup website kicks-in if the host goes down?

If not, does anyone else have some suggestions to handle this?

Yeah, i lost hours of production time due to the afrihost hosting being down.

This is possible it is called a fail over or fail safe. Im not gonna type out how to set it up so here is a link that will help you

I know my one site is hosted in the US doesn't make a difference really

This solution is open to split-brain issues because it's very asynchronous.
For example, if you have 500 MySQL transaction on the Primary site and then it goes down. During this period you do another 1000 transactions on your Secondary site, when the primary site comes backup you are left with the issue of "which database is more up to date". This is known as split-brain.

There is a much better solution if you are running your own dedicated servers or VPS.
Setup DRBD block replication for your sites files between Site A and Site B (http://www.drbd.org/) - This is a High Availability disk file system where it creates a RAID 1 file system across the internet.
Setup MySQL (Maria DB preferred) MASTER-MASTER replication between Site A and Site B.

With this setup, changes and updates to the primary site will be continually streamed to the Site B. When Site A fails and Site B takes over it will have an update copy of all changes. When Site A returns, the data will be synced back to Site A giving you proper data integrity.

Just my 5c :)
