Indeed.

Investing any substantial degree of hope in the availability 
of a single cable system is risky, at best. Although there's 
only two sub-sea systems on the east coast of Africa, as I 
mentioned on another list, it's better than one.

Experience has also shown that multi-system failure is 
possible, even in regions abundant in cable systems.

Diversity cannot be over-emphasized.

Cheers,

Mark.
