The service your providing for sky sports + is awful , your servers for the streams must be at capacity or your load balancers need looking at. This is very reminiscent of illegal streams where this kind of buffering is common place. I was excited for the EFL season to start but not so much now , that's 4 games I've given up on due to the constant stop/start. Before I get a generic response It's not my internet connection , I've rebooted the router and boxes , I've came off stream and back on etc etc. A very poor service due to lack of investment in the infrastructure. If you need help to correct this I know a man who knows a man that could potentially help. His been working with broadcasting servers for years and could show you a thing or two 🙂
