(just to make sure we're talking about the same thing)... You have a
director at one site (somewhere, lets say Toronto for discussion) and 8
(or so) web boxes, some of which are in the US and some of which are in
Canada.
Since real-servers are picked randomly, a client in the US would be
connecting to the director in Toronto and getting replies from machines in
Canada or US. Assuming your customers are well connected to the internet
(ie aren't coming in over slow or busy links), then the problem will be
how closely connected the two sites are to the internet backbone.
The only way to really know is to run tests. However since your access to
the internet depends more on the provider (reliability) and connection
speed, I don't expect you need expect more problems because your machines
are at 2 sites than 1.
