So if the reasons are neither technical nor financial, what gives?<BR>

So take a scenario - a provider is present in Rwanda and The DRC, and has direct physical infrastructure between these two countries.<BR>
<BR>
The provider's customers in both countries multi-home - both to the same African ISP who is in both countries as well as via a private international circuit to London (probably peering at LINX + taking IP Transit from another provider there, for arguments' sake). <BR>
<BR>
So what we're seeing in some cases is that traffic between these two customers "could" traverse their common African ISP for the lowest latency, but instead, both customers deploy routing so that their private circuit to Europe carries that traffic instead. So they end up "talking" to one another in a very foreign land, across several ponds, yet they could simply be talking that much closer, across a common border.<BR>
<BR>
One could argue that there is pressure to utilize expensive capacity that is in inventory, but the question is whether that requirement outweighs the performance gains or cost reductions that could be enjoyed by routing consistently and effectively.<BR>
