CW, got some results for YouTube for you (after our discussion yesterday).
Video is 1080p, unable to get up to 720p even. I displayed the stats in the corner, and this is what it shows:

(I took the vid out of fullscreen to take the screenshot quickly).
Last night (after midnight) it maintained about 7.5mbps, now it's struggling to get 3.5mbps (and even on that speed is unable to maintain 720p)
I know about the packet loss issue we're investigating, but at the same time as the vid I ran tests and during the time of the video test, there was no packet loss or high latencies on the exchange. TelkomZA is aware of the exchange issue we had yesterday though, and will hopefully look into that.
(What's interesting is that the video tried to jump to 7.5mbps right at the beginning - you can see the spike - but afterwards came back down to around 3.5mbps and stayed there)
During the day I tried to watch some tutorial vids on Office.com as well, and it kept on buffering, jumping between 480p and 720p, and even to 360p every now and then.
EDIT2: Tried the same video 5 minutes later, got these results:

Higher than before (why?), and then came back down (again, why?).
EDIT3: And the same behaviour on another video:
View attachment 164135. Starts high, then tapers off and gets lower as time goes on.
Traceroute using my CW account:

WinMTR on my Afrihost capped account (it's in bridged mode, so the first hop is the exchange here):

What's interesting to note here is the 3rd hop on the CW account. There seems to be packet loss there, which isn't replicated on the AH account. I am a little concerned with the "max" latencies on the exchange though, and will follow that part up with TelkomZA separately.
