I use virgin media at two properties. At one I have the 350 Mbps service and get around 380/37 Mbps - about a 10:1 up/down ratio
At the other I have a 100 Mbps service and get around 108/6 - not 10:1
I thought all services we being changed to 10:1 - is this correct?
Not correct. Tho it has been rumored for a while
https://www.virginmedia.com/shop/broadband/speeds shows the speeds. So if your on the 100 meg package at the other property then the speeds are correct.
