UPDATE:So it looks like the primary issue was Verizon and their ISP peering point. The HTML5 fix below did
fix the issue for a day or so, but it started back up again. Many other Verizon customers where having this same
issue. Verizon finally fixed this a few months ago and I have been good ever since.
Let me start by saying I love loved YouTube's html5 trial.
It was so great to be able to watch videos without using crappy Adobe flash. Being able to run videos at 1.5x and 2x was
just amazing. I started my html5 trial in the middle of last year sometime. It was going fine until about 3 or 4 weeks
ago.
The issue
I started having buffering issues with all my html5 videos. They would start to play and then would constantly stop to
buffer for more data. Watching the bandwidth of my workstation it was going at a max of 60K/sec down. That was not
cutting it at all. Usually YouTube gives you a big burst of data in the beginning of the video and then throttles it
back to a few hundred KB a second.
Who's issue is this?
I started checking my download speeds at speed testing sites and it was working fine. Checked my firewall and it looked
fine. I could not figure it out. About a week later I'm telling someone at work talking about my issue. He says
"That's funny I'm having the same issue lately". Another guy pipes up and says he was having that issue also, but he
had fixed it.
The fix
He tells me he finally narrowed it down to the
html5 test beta. Once he
dropped out of that the videos started playing with flash again and everything was back to normal. I told him
I would try that when I got home. Sure enough turning off the html5 trial fixed the issue. I could hardly believe it so
I decided to do a test.
The test
I used
Calomel.org's fantastic YouTube download script for my test.
I picked a video and downloaded it without being in the html5 trial. It downloaded an 85Meg video in about 5 seconds.
I go back in to the browser and turn on html5. Then download the same video again. I'm back to being capped at ~65K/sec. It was
taking forever to download. I killed that and turned off html5 again. Video downloaded in about 10 seconds this time.
Much much faster than being in the trial. One other thing I checked was this cool
YouTube speed test page. It said my avg bandwidth for the last
month was 14Mbps. So I know it was not my connection to them that is the issue.
Conclusions
By using this wget script it eliminated the browser and flash as being the fix. Just by being marked as being in the
html5 trial was the issue. It seems there is some issue with YouTube and html5 right now for a few friends and myself.
If I had to venture a guess at the issue, I would say they have code that will throttle html5 people differently from
everyone else and they have an issue with that code right now. I do hope it will be fixed. I know it worked fine for months
before this, so it should be possible to fix.

Google Suggested Website Tweaks
Google announced a new service they are offering called Page Speed. For
those interested here is the link for
everything they are offering. Google has also given out a
performance best practices
page which lays out a bunch of speed tweaks and how you can implement a lot of what this new service offers yourself. I found a
few that I implemented and I thought I would share them.
Pantz.org Site Tweaks
- Optimize Browser Rendering
- I specified image dimensions for all my images. This keeps browser redraws and reflows down.
- I specified a character set in my servers http response headers. This helps the rendering process start faster so there
is no character set guessing involved.
- Minimize Round-Trip Times
- I replaced my CSS @import line with a <link> tag. This allows the browser to download stylesheets in parallel.
- Minimize payload size
- I optimized my images with the Google suggested programs jpegoptim and optipng. On the banner image alone I had a
31% decrease in size. I could not see any difference in the image quality. Smaller is better.
Analyze Your Own Website
Google has made it easy for you to analyze your own web pages. Just go
here and put in your site. You will get back suggestions on how to optimize your website. I only have a few
suggestions left for my site and I don't think it's worth implementing them for a 1% gain on things like minify. If my
site was massive I might do it, but right now I don't think its worth it. This site is very optimized at the moment. It
better be as I built it for speed and compatibility. I think it excels in both.
