Just an update:
I have been experiencing slow speeds and packet loss for a couple of months now (Especially on google services like youtube, drive, etc.).
I PM'd the reps on this site and received no feedback. Subsequent to my PM, I logged a couple of faults through the Afrihost Clientzone - I tried to explained the problem and provided pingplotter data indicating the extreme amounts of packet loss I was experiencing. The data shows that the packet loss starts on/after the third hop on the MTN network. Here and there I experience some loss on the second hop, but 99% is from hop 3 onwards.
Naturally, Afrihost fed me the usual drivel about its not the Afrihost network (I think it is), please remove the adsl filter (I don't use one), you are currently 18% shaped - try using turbocharge (I have done this - still no change), my account has been checked and is fine (It is not fine), etc. I pointed out that all these solutions were already tried and tested without any luck, the issue still remains. I further requested that this be escalated to the "network specialists".
On 15 April 2015 I was told the issue had been escalated to the specialists - I have had no feedback on the problem since then.
I was further asked to run speed tests with different accounts - The issue as I described it was not about latency or speed, it was packet loss to specific websites. If the issue is a shaping issue on the Afrihost network (As it seems to be), these tests would be frivolous. To do these tests are utterly a waste of my time, and quite frankly pisses me off as Afrihost are not looking at the issue in front of them.
I have been running some tests with my VPN service recently and it is interesting to note that as soon as I connect with my VPN service all the previously experienced packet loss disappears. This leads me to believe that there is indeed an issue with the Afrihost shaping protocol/service and that my VPN in bypassing this.
I have subsequently cancelled my account with Afrihost as their support is too useless to sort out the issue.
I cannot afford to waste any more time sorting out an issue which I have no control over.
Good luck to the rest of you on this forum.
