Went live on fibre yesterday, so done a quick spped test, and it showed 23mb download and 1.9mb upload.
I was promised speeds of 40mbs before I signed up, but this is barely 50% of that figure.
I know TT say for the first 4 weeks they will monitor the line and make adjustments etc, but it will take a fair amount of tweeking to get to 40mbs!
