Effect of sub-Saharan African cable systems coming online
To show the effects of these cables coming online, we shall consider minimum RTTs and jitter. We should see a considerable decrease in the minimum RTT and jitter for hosts that have direct connection with active submarine cables.
MaIN OnE (phase 1) landing points, inaugurated July 2010
1. Morocco
We have three PingER nodes in Morocco. The node www.agpe.ma shows no particular change in minimum RTT due to MaIN OnE coming online. The node was experiencing problems before and during June but reappeared in late June. There were considerable spikes during July with minimum RTTs jumping around. This might be due to day/night differences in internet traffic. This could also be due to reconfiguration of routing tables because of shifting to new cable system. 
There is a noticeable difference in the minimum RTTs for the node at www.marwan.ma. The RTT drops from 250ms in June to 200ms in July and then stabilizes around 230ms from August onwards. It is interesting to observe the spikes in the month of June when the MaIN OnE wasn't online and the sudden drop in RTT during July. It is also interesting to note the stability of minimum RTTs after July.
2. Canary Islands
