I was made aware of a fault on the line back in November 2016 in Area 21, W5 post code. My 50Mb line has since seen average speeds of 0.8Mbps. This is comparable to dial-up. The fault is reported to be reviewed in February 2017! Is this typical for a fault to last this long?
I switched to Sky ADSL - I get 16MBPS and a 10ms ping, and it's a world of difference and cheaper. I am convinced the problems have been ongoing since I initially got Virgin fibre three years ago as 16MBPS is immeasurably faster than the '50mbps' has ever been.
