Based on my experience a couple of years ago while in West Africa: If you look at the BGP adjacencies and bidirectional traceroutes for ISPs in Sierra Leone or Liberia; Freetown and Monrovia are both are logically suburbs of London. Just with much higher transport latencies via the submarine fiber link and then transport from UK cable landing station to the IX points in London. The situation is a bit different in Accra, Ghana which is a much larger and more economically developed market, and has IXes and ISPs that peer with each other domestically.
