CDN is an "F" yet I use MaxCDN
My CDN score used to be a "C", but now it is an "F" yet I use MaxCDN now which was the same as before when I was a "C"...what could of changed? Secondly, would a sprite combine my js and css files...don't know much about that yet. Finally, what is the red solid line that is coming from a third party image on my site....do I need to contact the vendor for that plugin? http://www.webpagetest.org/result/100718_1HF6/
Thanks and I appreciate any feedback ![]() |

RE: CDN is an "F" yet I use MaxCDN
Do you have a link to your latest results? That way we can all be talking to the same tihing.
The red line is an error (something failed to load) - probably a 404 response. If it is being served by a 3rd party then yes, you should probably ping them. If it is for an image then you'd have a broken image on the page, if it was for something else then the result depends on what it is. A sprite will combine images together but doesn't do anything for css and js - those are actually a LOT easier to combine since you can just merge the files together (though on a publishing platform like wordpress it is more difficult which is why there are plugins that can do it for you). The CDN grade is a percentage of static requests that are served from a CDN. If you reduce the requests you control (which is a good thing) then the percentage of requests that are served by the 3rd party non-CDN actually goes up and makes your grade worse. This is one of the reasons I'm not a big fan of the grades because optimizing for the grades might end up backfiring. Thanks, -Pat |

Why is yslow or the San Jose test site not showing a CDN for my site when every thing else is ok?
