If you are looking to order a dedicated server from an overseas web hosting provider. The economics will vary from country to country. The bandwidth cost to server prices may cost more to purchase in whatever country you are looking at.
One of the main reasons for the higher price is the price for bandwidth and the limited number of providers. This results in higher costs to get the bandwidth to connect to the Internet. The same can also be said for getting the dedicated servers. Some overseas web hosts may order servers from the United States. While others may use local server suppliers. The prices for memory, hard drives, and other network gear may be higher compared to prices in the United States.
