My latest email to Afrihost:
Hi.
Thanks for the reply.
We're now going in circles. If you look the previous emails all the line stats have already been supplied.
To recap, there is nothing wrong with the physical line or the connection - I can stream youtube HD with any pausing to buffer. Speedtest results are all very good regardless of afrihost, afrigamer, or Telkom.
But other streaming sites such as gorrilavid seem to be severely throttled - this is supported by the fact that I can stream flawlessly from these sites early morning (6am) but not later on in the day or evening. And it's not a local congestion issue either as Telkom streams these sites flawlessly during the day when afrihost lags.
Again this is enough evidence that this is not a line speed issue, a router issue or anything else my end, but clearly a network issue.
And the fact that Pietermaritzburg seems to be routed through Kimberley? (looking at the speedtest.net distances between Capetown Jhb and Durban) still hasn't been explained.
The following fact also remains unanswered: I was able to stream flawlessly from these sites prior to the MTN migration, and I can still stream flawlessly from these sites using a telkom account.
