You'll see the time for your health check to the content servers,
which is essentially the time for network transfer, from the stats
page or socket. Obviously this time will impact the page load times
for your client.
Your own metrics for latency via curl or a # time "wget http://contentservers/expensiveresource" may be valuable.

The new host is placed at the backbone of our countrys internet and the ips can be moved to another host if needed. With this change we will be able to host our content servers and backup servers at any location and can move them around without updating all the domain names every time.
