Although I do believe it may be a congestion issue that everyone is experiencing, I find it strange as I have had some of the smoothest buffer free twitch streaming since the Vumatel DHCP server was upgraded in Cape Town which fixed the high latency in peak hours.
I do see lower speedtest.net results internationally compared to when I originally signed up 1.5+ Years ago but if I do bandwidth testing from my MikroTik to an oversea server I get my full speeds every time so I can't tell if it is a capacity issue or the service .i.e AWS/Twitch/etc does not have enough interconnect bandwidth with CISP/Upstream provider during the peak hours.
