Have you guys checked the routing we're on? Redundancy routes not the quickest route at all ... with all the "additional" hops to get from ZA to anywhere.
But alas... It's UP and WORKING ! ;-)
Problem for me is that im on a private wireless setup, so when international goes down wel all get dumped on a "backup" line which causes local and int browsing to be slow, not to mention the latency spiking through the roof.
