They admitted they never thought it would be this popular...
Bandwidth use going up by 10Mbps a pop makes load more spiky which complicates things a little. I expect the DSL side of things to experience similar issues with speed-matching if enough subscribers upgrade to 10+Mbps - it takes only 60 active 16Mbps subscribers to max out a 1GbE AHSSPI so 10GbE aggregation will become urgent there as well.
