AWS are launching a region in South Africa in "early 2020"

Azure also has pair of DCs in South Africa

but clearly the nortern parts of the continent will need more coverage.

I wonder what the continental fibre infrastructure looks like. Does most of the traffic go via a handful of choke points on the way out of Africa, and would traffic from Kenya to Nigeria (for example) go via somewhere like South Africa, despite the extra length of distance involved?
