Still, my suggestion still stands that Brazil could use a few more direct connections to other countries from around the world. A connection from Rio to Johannesberg, to give an example, would IMHO help both cities out and furthermore help the internet as a whole in a number of ways. It certainly wouldn't be fragmentation.
I fully agree, connections are good. I am not sure I would like Rio though, because Johannesberg is so far into South Africa, almost on the east side. What about Cape Town?
And by the way, what about this idea?
Lisabon Natal Cape Town?
Cape Town Natal is 6331 km according to Google Earth.
Cape Town Rio de Janeiro is 6073 km according to Google Earth.
Yeah, almost 300 km longer, but picking Natal would connect Europe and South Africa, probably meaning more traffic.
