Your problem is the countries network infrastructure not the physical location of the servers, for example here in the UK basically all websites will load quick, it's hard to tell just from page load speeds if a server was located 10 miles down the road from me in the UK, or across the pond in the USA. However Haiti is closer to the USA than the UK, so it's really not server location that makes the difference. Building a server farm in Haiti isn't really going to improve the speed of web services, what you would need to look at is getting better network infrastructure around the country and back to the main internet exchanges within the US. Normally the problems you face here is the price of sub-sea cable bandwidth is greatly dependant on the economies of scale; they typically want massive investments to drive the prices down to reasonable levels. Then when you have the off-island bandwidth sorted you need to build faster local infrastructure to get this bandwidth to your users. Once you have faster internet connections with decent global connectivity you will naturally start to see service providers build data centers out there.
