YouTube extremely slow + Possibly routing issues.

For the last couple of months I've been getting terrible performance from youtube and only youtube. Videos would load considerably slower than usual and buffering would take an eternity. I couldn't watch a video even at a 360p quality setting without buffering and I have a 6mbps connection. 720p videos used to load very fast and I never had to worry about buffering or preloading my videos at all. I used the Netlimiter program to monitor m download speeds through the browser (The program wasn't interfering or throttling my connection) and the download speed was horrendous. Typically slower than 1.5mbps. However if I go to another video streaming website like Dailymotion, HD 720p videos load perfectly fine and at full speeds.

 

When I tried Chrome versus my typical Firefox 4 browser the symptoms were the same. Untill I started using that built in DivX HiQ web player that replaced the youtube player for it's own claiming the video playback would be higher quality. The audio may have sounded better, but suddenly my videos would load perfectly fine. And I was watching 720p videos without a problem again. Now recently the HiQ player refuses to work anymore. Says it cannot download the video and that I should check my connection. Obviously I wouldn't be able to get to the page without a connection in the first place. I uninstalled it and tried to reinstall it to find that it is no longer possible to install the HiQ feature as DivX has stopped supporting it for months now.

 

Now I'm back to my typical terrible performance. I've tried every possible solution there is, I've cleared my cache and cookies. I've reset my broadband connection from my modem. I've called a technician over from AT&T to check my connection and setup and even replaced my modem a second time and nothing worked.

 

I've been looking at my trace routes from my network to youtube and other popular websites and the connection times out on the first hop after my modem every time. And likely will time out again several times after that. Here are my results that I just took.

The timeouts on hops 2-5 just indicate that AT&T has configured those routers to treat the ICMP requests as low (approaching zero) priority traffic.  They pass ICMP and all other traffic on to other devices fine (which is why hop6 and later are able to answer you).

 

There have been at times problems with either (1) the selection of the correct content provider near your network, based on what the DNS servers return and/or (2) buffering to some content providers.  This is normally localized to one provider (e.g. YouTube in your case) and/or a small geographic area.  For a while earlier this year it was Southern California and NetFlix.  Tempers were flaring.

 

You can try to call technical support and immediately ask for Tier 2, or you can send off to David and his team and see if they can help you with your specific issue with YouTube.

I have been haiving the exact same issue for months. 

 

It was really bad back in May, then it went way away only comming occasionally. I ignored it as Youtube being overloaded, but IMO I ask other people over  the phone if youtube wont load and they say its fine and they have AT&T. 

 

I am doing nothing else on my line, I have the 24/3 plan and I can hardly stream a 360P video... its super frusterating. 

 

Tonight its absolutly horrible, I have rebooted my router, pc, tried it on another pc, youtube simply will not work.

 

 

Then I go to vimeo.com or speedtest.com and everything is just fine. 

 

This one has me stumped, and I tohught it would go away itself, but as the OP has said, having this issue for months has gotten to me.

I'm having this issue. Have only noticed it for the last week or so.

 

YouTube is the site I use the most with my internet connection, and it appears that AT&T is throttling my connection to this site. Why am I paying for 12mbit service if whenever I try to watch online video it gets throttled to 1mbit or less?

Looking at the Youtube Help Forum, others are reporting the same issue.  It does not appear to be related to the ISP.

Ah, after all these years I did not know of their forums. 

I apologize At&t, maybe you are a good guy after all.

Show how often I watch YouTube.  I was also in the Navy in Hawaii at the time and may not have heard about it.

Well, I think I've figured it where the problem is and a possible solution or workaround. 

 

IPv6

 

For the last few months I've had cable company internet.  This internet does not have IPv6 protocol available.  I never had any speed/bandwidth issues.  This last Monday I had u-verse installed.  Right off the bat I noticed considerable problems with a few sites, i.e.. Facebook.  While in Facebook I had problems clicking on apps or  it would seem that Facebook was extremely slow to load.  It was as if Facebook or he apps would not respond.  Another problem I had was with Youtube.  I had what seemed to be a throttled internet on certain videos.

 

U-verse has the capability to utilize both IPv6 and IPv4 protocols.  IPv6 when available and IPv4 when websites don't have the option for IPv6.  (I'm assuming my previous statement is valid, I could be wrong.)  However, my assumption is that IPv6 is still buggy or is slower than IPv4.  Now, I'm not sure how IPv6 can turn a 12Mbs bandwidth to a 3Mbs bandwidth, but that's what I was experiencing while watching YouTube certain Youtube videos on 1020HD resolution.

 

The fix:

Turn off IPv6. 

 

After I disabled IPv6, everything I was experiencing as stated above went away.  I had no more troubles.  Every YouTube video I watched came down at my full bandwidth.  Facebook was nearly instantaneous.  Apps within facebook were loading just like they use to before I had u-verse.

 

The only caveat is I'm not sure if the U-verse router has the option to turn off IPv6.  I was able to disable IPv6 because all my computers and wireless devices are ran through my Cisco router.  My Cisco router does have the option to disable IPv6.

 

Disclaimer:

I'm not saying IPv6 is bad.  I'm just saying there is a problem or a bug with something related to IPv6.  IPv6 is what we are moving to.  It's inevitable.  Hopefully, we can get all the bugs out of IPv6 before it fully replaces IPv4.

 

Well, I think I've figured it where the problem is and a possible solution or workaround. 

 

IPv6

 

For the last few months I've had cable company internet.  This internet does not have IPv6 protocol available.  I never had any speed/bandwidth issues.  This last Monday I had u-verse installed.  Right off the bat I noticed considerable problems with a few sites, i.e.. Facebook.  While in Facebook I had problems clicking on apps or  it would seem that Facebook was extremely slow to load.  It was as if Facebook or he apps would not respond.  Another problem I had was with Youtube.  I had what seemed to be a throttled internet on certain videos.

 

U-verse has the capability to utilize both IPv6 and IPv4 protocols.  IPv6 when available and IPv4 when websites don't have the option for IPv6.  (I'm assuming my previous statement is valid, I could be wrong.)  However, my assumption is that IPv6 is still buggy or is slower than IPv4.  Now, I'm not sure how IPv6 can turn a 12Mbs bandwidth to a 3Mbs bandwidth, but that's what I was experiencing while watching YouTube certain Youtube videos on 1020HD resolution.

I have checked the router settings and there appears to be an option to turn off IPv6.

 

Home Network > Configure > IPv6

My recommendation is to turn off IPv6.  (only if you are experiencing troubles)  But then again that's why you're here, right?

I'm in Central MS and use AT&T for my home network.  I stand up a VPN with null encryption going to a box at work in West MS, which also uses AT&T but is obviously not a residential contract.  The box at the far end is configured to proxy.  The problem continues -- again, only impacting download performance for YouTube and NetFlix.  I cycle the VPN to use encryption and the problem stops entirely.  I've since done the same with VPN endpoints in VA and Northern IL and gotten the same results.

 

Without the VPN, or with the VPN but without encrypting, I get less than 1Mbit rate for the first connection attempt and stalled connections for all subsequent attempts.  Reboots for local box and DSL router, clearing of cache/leases/cookies, etc, do not help.

 

Hiding the nature and content of the requested destination from geographically local AT&T management immediately fixes the issue, without fail, repeatedly, over the last several weeks.
