Amazon CDN

Amazon CDN
I am using Amazon (S3 / Cloudfront) as a CDN for some of my content. I would love to get webpagetest to recognise this CDN usage. Exclamation

RE: Amazon CDN
WebPagetest should recognize cloudfront already - do you have a test result where it doesn't? S3 isn't a CDN by itself so if you have any assets being served directly from S3 those will fail.

Thanks,

Thanks Patrick, I will double check that its the Cloudfront URL and not the S3 URL thats being referenced.

RE: Amazon CDN
Amazon CloudFront ain't working with webpagetest at least in my tests. Tests from different locations are getting served from the same location over and over. I don't use S3 at all.

I successfully verified my CDN was working properly with the following sites

http://3.ly/UA9V

Nevertheless - this is a great site and has been very helpful to me. Thanks!

RE: Amazon CDN
Do you have a test page you can share (PM or mail it to me at pmeenan@webpagetest.org if you don't want it public)? If there is a problem detecting a flavor of cloudfront I'd like to get it fixed.

Thanks,

I've got a test page (gwa.reedbusiness.net/test/gwa.html) on Amazon cloudfront. Webpagetest reports traffic as being served from the US (Seattle, WA) while I'm testing from the UK. Is the reported Location correct?

RE: Amazon CDN
The location reporting for CDN POP's isn't very accurate, it usually ends up pointing back to where the company is based instead of where it is really hosted (the MaxMind IP database is pretty good for hosting providers but not so much for CDNs). Check the socket connect times to the node and see if they look reasonably fast (subtract 50ms if you are using the typical 1.5Mbps ADSL profile). It should be pretty easy to tell if it is going all the way back to Seattle.

In the next month or so I plan on adding traceroute diagnostics from the testers as well which would help in diagnosing CDN issues as well.

Thanks,

-Pat
