Dustbury notes some commentary on the fussin' between Verizon and Netflix about network capacities and streaming speeds. You will be unsurprised to learn that each company claims the other is at fault in the matter.
I have to say that I have noticed no problems with my Netflix playback. But then, I'm still getting physical DVDs in the mail, so my watching is not affected by download speeds.
If the Post Office runs slow, on the other hand, that will have a definite impact.
