Up to 1000 Mbps - yeah, perhaps if you have built your house right on top of the cabinet. In fact, not even then.
I was on their FTTC product for a couple of years, the one that's "up to" 80 Mbps. I got 18 down and 0.75 up. I tried reporting the speed to them on several occasions, especially the upstream speed which was very limiting, only to be told they didn't consider that to be a problem - it's within the range of speeds considered acceptable for that product.
