I know Caida has one paper on the congestion on Africa's IXPs substrate. However, we did find Kenya, Nigeria and South Africa have better transnational performance than China, while the performance of Ghana and Egypt was worse than China, at least that's what we saw from the web4africa VPSes we brought.
We've seen somewhat similar behaviour from these networks when peering outside of China
Sorry I am a bit confused here. What do you mean by "these networks"? When you say "peering outside of China", who is peering who exactly?
