We have contemplated a POP in Kenya. We will get there. Johannesburg should be less than 200ms, so let me see if I can improve that... I would expect about 100ms.
JHB is much further away from Europe than Kenya, though.
JHB means usually going to Cape Town first, then up the west coast of the continent, wheras Mombassa uses SeaCom, going around the east of the continent. That saves a lot of time from a pure distance perspective alone.
