On SAIX ADSL, you could have been routed more directly. On IPC, it depends where the ISP has a PoP. We haven't been able to justify the investment required for a PoP in Durban yet, so you go through Gauteng ... It is designed to we could (relatively) easily move the PoP.
Of course, on SAIX ADSL (shaped), your international traffic would have gone to Rosebank anyway, so we haven't made international latency much worse (maybe 4ms), but we did improve it for users in Cape Town (who should have a shorter path to international sites, by 20-40ms).
Thanks Ranger. So basically us Durban clients just have to put up with slightly higher latency than Gauteng and Cape Town users?
Not that 43ms is very high at all, in fact when I was with MWEB and Buzybuy my pings were around the same 40-50ms mark.
