Ookla’s Net Index shows that Parow is the suburb with the highest average broadband speed in South Africa, followed by Witbank and Sandton.
Ookla’s Net Index uses data from the web based speed test service Speedtest.net. The service ranks consumer download speeds around the globe using results from the past 30 days where the average distance between the client and the test server is less than 300 miles (482.8km).
Results for South African download speeds were obtained by analyzing data from 280,820 Speedtest.net tests which were performed between 13 November 2011 and 12 December 2011. City (suburb) rankings require at least 1,000 unique IP addresses for a given city.
- Parow 9.37 Mbps
- Witbank 5.02 Mbps

- Midrand 3.86 Mbps
- Bellville 3.68 Mbps
- Randburg 3.62 Mbps

It should however be noted that the average speeds are calculated using all Speedtest.net results which may include speed tests from core networks and other non-commercial broadband links.
The high average speed in Parow of 9.37Mbps, for example, may well be a result of a high number of tests from high speed connections other than commercial broadband services.
