Still really thin with details of why. At least this says that they are 
NAT'ing v4 at *their* edge. But 99% of the lag of filling your newsfeed 
is their backend and transport, not connection times so who knows what 
they are actually measuring. Most NAT'ing is done at the consumer end by 
your home router in any case.
