Speaking from my CDN and service provider hats, I'd say upstream 
congestion.  If you're an end user with a gigabit internet connection, on 
a service that presumably has lots of customers with similarly large 
connections, it's a safe bet nothing upstream of you is provisioned with 
enough capacity to serve everyone running full speed.  Whether it's 
peering with the CDN, backhaul on your provider's network from the peering 
point to whereever you are, etc.  Something, or multiple something's, will 
run out of pipe in a traffic event like yesterday's.
