Good. I swear youtube is throttled by Time Warner Cable for me. I stream Netflix, Hulu, etc and never have problems with them. I can confirm that I'm getting my speeds of 20MBit/s down, and yet almost every video on YouTube buffers. If I use youtube-dl to download the video, I can confirm that my actual connection speed is somewhere around 60KB/s. If I then use youtube-dl on my VPS with the same video, I get somewher…

I'm really surprised nobody's mentioned peering/transit in this thread. Ars has a good set of write-ups on this topic, the latest being http://arstechnica.com/information-technology/2013/07/why-yo...

Whether it's the fault of (1) the residential ISPs for letting their ports run so hot, or (2) the transit providers for trying to stiff them on pricing for additional capacity, or (3) the content provider for choosing a cheap upstream who is known to engage in this activity is up for debate!

As someone else noted on another thread, it's remarkable how often the name 'Cogent' comes up in these kinds of issues...

That's confusing. It listed the 9 ISP's in my area... and the local power company. The power company's graph looked completely different from the ISP graphs, of course.

Anybody knows why recently Youtube re-buffers every video when I hit replay? It might make sense for long videos but for relative short videos (music videos and the like), it's really frustrating.

It's because Youtube uses DASH[1] by default now. It's also the reason why it never buffers more than a few seconds of video anymore.

I installed YoutubeCenter[2] and disabled DASH from the options and it seems to work well every since.

They probably do it, but Google is at fault, too. Their new DASH thing has made the experience so much poorer. They never should've done it to begin with, and I don't think whatever savings in bandwidth they might have from it are worth the compromise. Youtube was perfect before, because it allowed you to cache videos, and go back on the videos whenever you wanted, with no need for reloading or whatever. DASH made it…

All of that is required by their advertising business model. The more YouTube emulates the pre-VCR TV world, the more they can charge for time and visibility.

Is it me, or is this website subtly paying homage to Sen. Ted Stevens' famous "Series of Tubes" anti-net-neutrality speech.

People talked about Internet "pipes" for many years, but somehow Stevens was a moron for saying "tubes".

It's a not-terrible but very basic metaphor applied to an area of engineering which about 99% of his audience did not need explained to them with a very basic metaphor. People assumed that it was he who needed the metaphor, and... hilarity ensued.

Brighthouse (TWC subsidiary) throttles quite a few services these days, Youtube being the biggest one. The throttling is so intense 24 hours a day that Google's streaming algorithm (download a little, play a little, repeat) can't continue downloading after the first initial burst. I can easily break it by VPNing into Work or School. They very recently started throttling Netflix. I have a 90mbps down connection, and I…

Google is smart to Name and Shame the bad ISPs. I just think they should build this into the Youtube player, whenever the buffering spinner lags for more than 5 seconds have a a little message fade in that explains what the hold up is.

Interesting. Couldn't they just run a tracert and, through broad data comparisons, prove quite elegantly what the holdups in the chain are?

I can't even work on my regular job or projects without seeing at least 4% packet loss, intermittently spread out across the day. Not only that, I clearly see pings taking too long even with wired connection. Comcast has told me they cannot do anything about it. They say that the 2 MacBooks and a couple of iPads is a lot of traffic for the router+modem they have given me.

Not only this, I know that the moment I start Youtube or Amazon instant (I do not have Netflix), the packet loss starts to go up or at least the ping return times sometimes go up to 4000ms. This also happens when I RDP into my Windows PC at work when I telework.

I have tried resetting the router, use it with other channels, use it with and without all possibilities of encryption (WPA, WPA2 etc.) and I really cannot think of doing anything anymore. The Comcast representation said they will reimburse $30 bucks if I got my own router because the issue is not their fault.

I am not sure how to approach this issue anymore. My apartment building does not have Verizon FiOS or any other service. I have given up all hope. Sometimes I feel like adding unlimited LTE/4G on my iPhone from T-mobile and use that as the main Internet hub.

Earlier quoted context omitted.

I think Comcast is doing the same thing here in Colorado. Lately, I've been seeing quality drop in videos where it shouldn't. Running speed tests or downloading from newsgroups I'm hitting 60mbps.

You'll be happy to know that Comcast's Denver ibone switching/routing has been over capacity for many months at this point...Same goes for their Oregon switches (which service SV and the PNW seaboard)

http://ispspeedindex.netflix.com/results/usa/graph Looking at comcast over the last two months looks like there is some data to confirm your notes about their backbone having issues. They are on a steady decline.
