And Telkom are using such a tiny portion of that.
It would be nice to know for certain how much is being used. Damn cartels.

These stats are a nice bit of info to keep on hand.

25% is being used: http://strategis.ic.gc.ca/epic/internet/inimr-ri.nsf/en/gr117294e.html

Also, 100,000 DSL users with 3GB cap using pure 100% international traffic only could not reach 1% of the total available bandwidth, even if they all max their caps and use no local bandwidth at all.
 
So we can easily have 300gig caps for each user before the cable will be fully utilised. So much for international bandwidth shortage.
