Time Warner Cable YouTube throttling

I've been seeing the same thing and was thinking it was me.
Just to add to some of the results here...

It would be nice if the ISPs and content providers could work out something when dealing with this much traffic and clearly needing to add capaicty. It's nice to dream too...

I think your trace routes are just to their web servers. You need to figure out where the actual videos are being streamed from. I used the Developer Tools (Network tab) in Google Chrome to figure this out. The FQDNs will probably look like the ones in my trace routes.

Yup... This might be more helpful.
I went to r19.sn-p5qlsm7d.c.youtube.com for better comparison.

Jumping into the bandwagon here to help out.

Here's the result from RIT to r19.sn-p5qlsm7d.c.youtube.com, going through
at least 4 hops through XO territory.

RIT is probably on a commercial circuit and from what i have seen on this
chain so far, it is only affecting home/consumer users. At MSOE (msoe.edu)
i dont show any latency but we are on TWTC. Anyone chime in if that is
wrong.

Also if your upstream has Google Global Cache (or whatever it's
called), the results can be very different I suppose.

Does Google use different naming structure for IPv6 CDN? Maybe this
particular cache does not offer IPv6.

Level3 peers with Google, I am curious why it hand the traffic off to XO.

I had the opportunity to look at this from a TWC fiber customer in Ohio, and this did not seem to affect them.
