South African Internet Exchange
The South African Internet eXchange (SAIX) was a transit ISP erroneously marketed as an Internet exchange point. It was once the dominant provider serving Internet traffic in Southern Africa. SAIX is run by Telkom, a semi-privatised South African company. At one time SAIX provided service to two-thirds of South Africa's ISPs. However, since deregulation that has declined to the point of insignificance.
