A couple of potential reasons a network could do this:

	1. They don't have enough bandwidth to the exchange
	   point, and as such, are using routing to control
	   how much traffic is loaded locally. In fact, it
	   is possible they have less bandwidth to the
	   exchange point than they do internationally.

	2. The provider is assuming that the majority of the
	   audience that his hosting service is serving are
	   not in Africa. This is a fundamental issue which
	   I'm not sure can be resolved here :-).

	3. The provider could be withholding those prefixes
	   from settlement-free peers, but can make them
	   available to customers who are willing to pay
	   money for them, i.e., either as IP Transit
	   customers or as paid peers.
