Google throttling YouTube streaming based on Google account and UA string.?

I am going to layout some other work-around’s I’ve not mentioned here in another post. One has me scratching my head.

I am going to also recap my system, software involved and test methodology just so I make sure all understand the issue but also understand the possible regional nature to the issue.

But for now checkout the difference between using a ‘Private Window’ and a ‘Normal Window’ in FireFox. As with my previous test the results are interesting. Lately throttling has been starting around 5:00pm CST Till 12:00 am even later. This test was done was around 5:00pm CST

Here I am viewing a ‘live’ stream from YouTube at 360p. I am ‘NOT’ signed into a Google account. I am using FireFox with a ‘Private Window’. You can see the data burst is even, regular with peak burst rates of over 1mbit/s.

Here I am viewing a ‘live’ stream from YouTube at 360p. I am ‘SIGHNED IN’ to a Google account. I am using FireFox with a ‘Normal Window’. Notice the bit-rate pattern now. Continuous, with an irregular distribution of data and an average peak data burst in the 250kbits/s.

So a workaround in FireFox for me is opening a video stream into a ‘Private Window’ In fact I can steam in the private window with no throttling and in the normal with throttling at the same time. Side-by-side! So crazy; one’s being throttled the other is not and with the same ‘live’ stream in the same web browser and plugins.

Interesting.
