This from our backbone providers – please note that the new Windows 10 update mechanism prefers not to offer update options and thus can cause massive network congestion.
We have experienced a sharp increase in network usage due to the latest windows update that was released yesterday. We are experiencing intermittent speed issues and latency increases. Our engineers are doing everything possible to try and mitigate the impact on our network. We thank you for your patience. We would suggest updating your windows over night to reduce the impact it has on your day to day activities on the net.
