A faster able2know. We are now using a Content Delivery Network

Some of you may have noticed some missing images today for a brief period, and what you were seeing was a transition where we began to use a content delivery network. To the non-techies among us what we did was move all our static content (images, JavaScript, CSS, etc) and host it with a distributed Content Delivery Network.

This should help to make able2know a bit faster by removing the need for the static content to be served by the same servers that serve the application content. We can also make those files download more quickly by using a network optimized for download speeds where the files are hosted around the globe in order to bring them closer to the users around the world.

We are using Amazon’s CloudFront network for able2know’s CDN, and this means our static content is now being served out of the following locations:

United States

  • Ashburn, VA
  • Dallas/Fort Worth, TX
  • Los Angeles, CA
  • Miami, FL
  • Newark, NJ
  • Palo Alto, CA
  • Seattle, WA
  • St. Louis, MO


  • Amsterdam
  • Dublin
  • Frankfurt
  • London


  • Hong Kong
  • Tokyo
Hopefully this made browsing able2know a little faster for you, and even if you don’t immediately notice things like that they add up and we will continue to work on making able2know even faster (hey, we are hardcore web performance geeks, this is what we do). Let us know if you notice anything amiss from the CDN roll out and here’s to hoping the changes bring about a slightly speedier able2know for you.
