You would be getting DSL line sync of 5088Kbps at a distance of 3.5km. But this is also dependant on the equipment that you use, congestion on the network or the weather. The condition you are referring to i take it would be the Telkom infrsastructure. The problem could be at any stage of your DSL connection route - your PC, local network, router, Telkom exchange or with the destination server that you are trying to access. If the problem was on our network, we would see several clients with similar experiences, which we are not at present. If your latency is high at the first hop (to your router) it is either a problem on your PC, local network or router. If the second hop is high (in the traditional setup) this usually points to a line fault or an exchange fault. If the latency is high only at the very last few steps of your trace, then the problem could be on the destination server or the hosting network.
