In case you haven’t heard, Uptrends has a new, exciting free tool, CDN Performance Check. The new tool makes checking on your CDN performance super easy. Plug in a URL for your site or one of your static resources and watch as Uptrends times the connection and download from over 40 worldwide locations. It’s one quick test, but you get so much CDN performance information back. All you need is your site’s URL or the URL for one of your static page elements served up by a CDN. If you don’t use a CDN, but you want to know how well your site does when responding to a request, paste the URL in the domain field.
