How to place one site on two accounts within the same hosting so that it works?

Question

Network administration

It was necessary to place the same site on different accounts within the same hosting. In order that if one ceases to work normally, switch to the second.

Answer 1

it is possible, with different domains.

Answer 2

The site can be hosted, but the domain at 1 point in time can only point to 1 place, and in order for the site to load from 2 places, something like a load balancer must be set forward. Why do you even need such bullshit?

Answer 3

interesting. That is, on different servers. It is unlikely that this will happen on hosting, because there are no proper synchronization between servers, or do you have your own data synchronization scripts?
Or do you have static sites? Do you understand what I mean? For example, a comment was left, it is necessary that it be immediately copied to the second server ...
