I have tested on 5 different speed test sites. Just a quick note though frogfoot set up a connection where i could plug straight into the ont and connect to them via a special ip adress they set up, they ran the speed test om my pc over teamviewer and boom goes to 900/900 but as soon as i go to the normal connection through ncloud i get nowhere that speed.Vary the speedtest server that you are using. Many hosted speedtest servers in South Africa especially in Slaapstad are not very good at measuring high speed as they are installed on a VM attached at 1gbs. And they don't see the point in upgrading to 10gbs. Also would help if they put those servers on bbr.
Use afrihost, MTN and Vodacom as examples.
