Please don't create confusions.
I didn't made any assertion. I mentioned issue with India, but Graham came
with point that issue is similar in Africa. Good point if he knows that.
Certainly relevent to issue I mentioned for India.
Again - I have not verified this. I don't know much about ISPs in Africa to
find their looking glasses and test routing.

Ok, here's some data I collected couple of months back. I did consistant
lookup for days to be sure that it's not temporary routing glitch giving
such results.
