573936 - Host Getting Started videos on our EdgeCast CDN

Status: VERIFIED FIXED

(www.mozilla.org :: General, defect)

Description

Now that this page gets a lot of traffic (it's the Getting Started page, after all), I've noticed that initial play of the videos here, http://www.mozilla.com/en-US/firefox/central/, can be quite slow; we should host them on and link them to videos-cdn.mozilla.net, which resolves to our EdgeCast CDN.

+1 from me on this

Steven, when working on the new Getting Started page, did you incorporate the optimization suggestions from https://bugzilla.mozilla.org/show_bug.cgi?id=571990#c0? This seems somewhat connected to that.

Maybe it's just a local issue, but I seem to get between 300 ~ 500 K/s from videos.mozilla.org, and less that 10K/s from videos-cdn.mozilla.net. Can anyone confirm?

Must be a local issue?  I'd be surprised if our own hosting would ever be faster than a global CDN:

Thanks for confirming the speed Stephen - I tried again today and I'm not seeing any performance problems with the CDN. I blame solar flares...

Video URLs have been updated to use the CDN in trunk in r69446 and merged to stage in r69447. One file to push to production: en-US/firefox/central/index.html

Should we do this for all videos on mozilla.com that load from videos.mozilla.org? (new bug?)

Verified FIXED; bug 564879 should take care of comment 5, or we can file individual bugs, if need be.
