Netflix stuffing data on pipe

[mhoppes at indigowireless.com (Matt Hoppes)]

Has anyone else observed Netflix sessions attempting to come into customer CPE devices at well in excess of the customers throttled plan?

I'm not talking error retries on the line. I'm talking like two to three times in excess of what the customers CPE device can handle. 

I'm observing massive buffer overruns in some of our switches that appear to be directly related to this. And I can't figure out what possible good purpose Netflix would have for attempting to do this. 

Curious if anyone else has seen it?
