Here's a hilarious article from Verizon to dispell the 'myth' of issues getting what you have requested from Netflix:

Here's my favorite part:
"One might wonder why Netflix and its transit providers were the only ones that ran into congestion issues. What it boils down to is this: these other transit and content providers took steps to ensure that there was adequate capacity for their traffic to enter our network."
Last time I checked, Verizon sells internet service to its customers; i.e., pay us and we give you access to whatever you want on the internet. It is their job to ensure that I can get the content I am paying them to deliver to me. It's ludacris to expect every content provider on the internet to investigate whether or not every internet provider on the planet has a network engineered to be able to receive large amounts of traffic from them.
I love how Verizon calls the traffic "their traffic." as if Netflix is magically sending something to them uninvited. No Verizon, the traffic in question is not Netflix's traffic, it is my traffic. I pay you for internet service, and I pay Netflix for movies, delivered in the form of packets of data across the internet. When a unicast stream of movie data leaves Netflix's servers, it is mine, I paid for it, I pay you to deliver it from them to me, and you suck at doing that during busy times of the day.
