I expect the 25Gbps link to be over-subscribed. Without minimum bandwidth guarantees, with 48Y4C * 2 switch and 100Gbps backhaul to the whole PoP (with minimum 64 customers for it to break-even), I suspect the sustained bandwidth will fluctuate wildly. In the worst case scenario, each customer may get a sustained bandwidth less than 50Mbps. Of course the big advantage is burst bandwidth is much higher.
