If I understand you correctly. Your office will host your client's webserver a
s a backup ( incase
both of client's ISP connection goes down or client's web server goes down ).
This can be done in many ways. using global DNS load balancer is the simplest
way i can think of.
basically when someone on the internet request for your client's address. The
DNS load balancer can
be configured to check for client's web server ( ie ping or web get ). If your
client's web server
is responding the DNS load balancer will resolve to client's web server's IP.
but if your client's
web server is not responding, it will resolve to the web server IP address co-l
ocated in your
office.
It depends on what kind of redundency you want, There are many ways to implemen
t this.
look into http://www.f5.com if you need information on load balancers
just my 2 cents
