Re: Time Warner Cable YouTube throttling

[Elijah Savage <esavage () digitalrage org>]

Jumping on the bandwagon. I have not had the chance to follow the entire thread but have seen this behavior from AT&T 
Uverse, Time Warner, and Verizon FIOS. I believed initially this was a capacity issue with Google and Youtube. The 
reason for this thought is fairly simple with no scientific troubleshooting invested at this time. I can replicate 
slowness on AT&T Uverse and Time Warner at the exact same times, the anomoly is Verizon FIOS does not align with the 
other two. 

When there is slowness on Uverse 99% of the time my Time Warner connections to Youtube will be slow as well even if you 
are streaming different video's.

Subject: Time Warner Cable YouTube throttling


We have recently been having some serious speed issues with YouTube on our home connections, which are all Time Warner 
Cable.
Some searching on forums and such revealed a work around:

Block 206.111.0.0/16 at the router.

This makes speeds go from ~1 Mb/s to the full connection speed (30 Mb/s in my case). It appears that TWC is forcing 
traffic to this netblock over a congested link, or otherwise throttling it.

Trying to communicate this to tech support results in the typical "Derrr, what?"

Does anyone at Time Warner care to comment on WTF?


thanks,
