2 edits | Youtube+HD videos SLOW streaming is back. :( What is the deal with Youtube? I haven't had this problem for awhile but since yesterday it seems most of their videos take FOREVER to load.
Was just trying to watch this video in HD
»www.youtube.com/watch?v=GrMwV-FOq60
And it keeps pausing..yesterday I was trying to show a buddy of mine a video and we ended up waiting like 10mins for it load up so I can play it. Then he even said hes seen Youtube loading slow while he was visiting his sisters in the next town over.
Looks like they need more servers for the demand..unless its Comcast routing or their throttling? I doubt the throttling part though..but you never known with this company. |

Los Lunas, NM | Re: Youtube+HD videos SLOW streaming back.. I have had problems with youtube as well. I don't think it has anything to do with Comcast. Considering on several servers as well as torrents I am able to get full speeds as long as there is enough available bandwidth. Youtube may be having trouble balancing their load between whatever servers/lines they have.
The problem may be new for you, but I have experienced this for many months.
p.s. In the time it took me to type this reply the video didn't even finish loading with SD. |

kudos:5 | Recently over the last few months I have seen many Google sites start to show degradation in speeds from their servers. And not just YouTube either. Gmail and Google Reader also show spurts of slow response.
Not sure what their problem is, but I am still getting very good speeds from many other sites. I doubt Comcast is causing this problem. I suspect that the much ballyhooed Google data centers are starting to get overloaded and they aren't expanding fast enough to handle the load.

Same here and it started yesterday. It's a little faster today, but still slow. |

I'm seeing this as well - almost makes YouTube unwatchable.
However, it performs fine on my t-mobile phone... so it seems to me that it's likely the pipeline to Comcast or something on Comcast's side. |

Thought it was something here on my computer but I am experiencing this also. |

From the time I clicked the link, it took only 2 1/2 sec. to start playing and did not stop or buffer. I had no issues.

| I watched a dozen videos related and the only issues were some loaded about 4 sec. Still no issues. Sorry!

Have the YouTube problem here as well. What's funny is that Vimeo is fine, and I'm pretty sure watching vids through my Sprint phone are also fine. So it's some sort of routing/internet bottleneck problem.
Which, I agree, is freaking annoying. |

Content distribution networks (Google, Youtube, Akamai) use global load balancing through DNS, so using resolvers outside of your ISP's network can result in suboptimal balancing across the content caches.
Using popular DNS services (ie, OpenDNS, the Level(3) open resolvers) can actually result in overloading of a particular content cluster.
I detailed a bit about how this works here:

1 edit | I'm using Comcast's DNS just for reference.
Also, the servers are the ones for the "Opt Out for redirection" |

Yes I've definitely been noticing it. It gets really bad in the evenings. I suspect it's just heavy traffic bringing their servers to a crawl. |

Sometimes I just pause the video so the buffer can get a bit ahead of the play position. |

Boynton Beach, FL | As a quick test it might be worth doing...
1) Trace route to the YouTube server using OpenDNS
2) Switch your router DNS back to the Comcast DNS servers
3) Verify the test computer is now using the Comcast DNS servers
4) Trace route to the YouTube server (using Comcast now)
5) See if the problem persists when viewing videos
If the problem doesn't persist, posting both trace routes may yield a bit more information. |

OpenDNS, Comcast's DNS servers, Level(3)'s 4.2.2.x servers are all what are known as recursive resolvers. What that means is that you ask it to resolve a DNS name, and it does the full number of queries it takes to get a final resolution and only returns the final result to you.
When you look up "www.youtube.com" that upstream DNS server needs to query the root to find out who to ask about ".com". It will find out it needs to query the g-tld servers, so it sends a query there asking about "youtube.com" -- that server points them to YouTube's DNS servers. YouTube's DNS servers aren't standard DNS servers though -- the next query they are going to get is a request of the IP of "www.youtube.com" -- but they don't respond with the same IP to every query. The global load balancing servers use the IP of the server who initiates the request and respond with the cluster IP that is likely to have the best network performance back to the network the DNS resolver is on.
That last part is the problem. OpenDNS is doing the query on your behalf to YouTube's servers -- and YouTube is going to respond with the server that has the best performance back to OpenDNS, which may be a completely different cluster from what one that would have the best performance back to Comcast. If you use Comcast DNS servers, then YouTube will identify the destination network as Comcast and return the IP of the cluster that has the best possible performance back to Comcast.
OpenDNS and the like work great for fixed IP addresses. www.dslreports.com will always return the same IP because it's only hosted in one location: nac.net. It really screws with global load balancing, however, because those services make the assumption that end-users are using their ISP's DNS resolvers. |

I've had no problems with YouTube videos, and I'm on Comcast DNS servers. |

I'm sitting on a 20/20 Fios line, and have no trouble hitting (close) to that speed. But for the past few MONTHS, I have to start a Youtube video and hit pause for a good 30 seconds for it to buffer enough of the video for steady playback. If I don't it stops the video every 5-10 seconds to catch up.
