are spread all over the world. When a surfer goes to YouTube the yes again
a cluster of DNS servers determine the fastest (not always shortest) route
to the surfer it's ip address Based on that result the dns cluster returns to
the surfer's browser the ip address of the loadbalance cluster which then
relay the request to a server node in the webserver cluster.

each link in the chain is built up in a cluster grid monitoring eachothers status,
load, response time and speed. All requests are being relayed everytime to
the most efficient node at that time.

I have no clue why I'm explaining this here I guess I'm bored or should I say board?
