Unstated, but about half the industry norm and lower on average. Network operates uncontended for the most part and we're only seeing some occasional contention in consumer peak hours when people are firing up streaming and downloads. Since the Netflix DNS crackdown we've seen a massive spike in NNTP and P2P downloads from 6pm onwards rather than the suggested midnight window. However it's unlikely many people have felt this to any large extent as we intelligently manage the network when this happens so as to avoid contention being experienced from the end user perspective, as much as possible. Even then, it's only download protocols that dynamically scale up and down in speeds and will burst full when there is spare network capacity.
One of the ironic twists in having operated the network unshaped and uncontended for about 7 consecutive months is that people now believe that this is the expectation, and it's important to remember that when the network occasionally contends, home uncapped for example will shape downloads according to priority, with basic accounts shaping first, and then only moving to premium shaping if needed thereafter. Furthermore there is intelligent management in place that determines which accounts to shape and which not to, in order to mitigate against feeling the impacts as much as possible. Even further, the shaper will target the heaviest users first so as to preserve capacity for those who don't really deserve any network management being applied...
