Mrdenny is correct, we don’t understand your question. Can you give us more detail as to what you are trying to find out? Are you asking what impact your servers will have if you open up offices across the globe to connect to it? As long as the WAN link is stable then there should not be issues depending on how many users you plan on adding onto the system load. You might have to ramp up your server farm with virtual servers using such products as VMWare so that there are enough network services for the entire organization to use. Possibly setting up multiple email servers or server clusters to handle the load. You would also have to look into redundancy on the network links. The world is feeling the impact of not having redundancy when 2 of the main oceanic fiber lines were cut just north of Egypt. Since two of the main lines were cut companies were feeling it since both their main and backup lines were down. here is one article on it: FoxNews.
