Feedback i got was that line and exchange seems fine. Internet working fine during the day but come night time, streaming bad quality and buffering.
In JHB North, same problem. Except my daytime speeds used to be fast and deteriorated to virtually unusable in recent weeks.
I even had intermittent connectivity issues last week. Logged fault online. Telkom technician was at the premises less than 24 hours later, tested OK. A second technician turned out on Saturday morning - tested again - line OK, no noise etc.
Intermittent connectivity solved right now.
I contacted TelkomZA to help investigate and was simply blown away by the service I received from Charl. My line was diverted to another 'box' in the exchange within the same afternoon (I actually watched the router disconnect and reconnect as they did the divert) - it was confirmed as congestion problems.
Deanoblado - if your JHB North after hours speeds test slow on speedtest.net - investigate for exchange congestion.
Afterwards:
Daytime speeds immediately improved to normal - maybe also partly because schools have re-opened
Here's the problem:
From about 4pm onwards and weekends, browsing and YouTube streaming 720p, also no issues, BUT... other methods of streaming mostly slow and buffering.
NOTE: this is the same on TI uncapped and Afrihost and FNB capped test accounts across the board, so imo not ISP related.
Speedtest.net and MyBB's version thereof almost ALWAYS gives me fast local and international results, no matter what time of day, so like I said before, this is not an accurate speedtest for me, ever.
I suggest using
http://speedof.me/ - if you get good results, you will be able to stream 'alternative' services than YouTube at 720p, if not, then you will most likely see YouTube and the likes still work full speed, but not the alternatives based on DNS-region changes etc.
In the past I used to simply switch to capped accounts and speeds immediately improved for streaming. At present, doing this makes no difference. Streaming remains buggered until about 11pm onwards where some nights it improves.
Question for me is: is there suddenly some 'invisible hand' now controlling/shaping/throttling in another way non-ISP related?
