Cloud Files Enhances Scale And Security Of Our Content Delivery Network (CDN)

Filed in Product & Development by Megan Wohlford | August 3, 2012 1:09 pm

In an effort to continuously enhance the scale and security of our Cloud Files and CDN products, Cloud Files will be changing the format of our CDN URLs.

The good news is that ALL EXISTING CDN URLs WILL CONTINUE TO FUNCTION AS NORMAL even after we make this change.

Beginning in mid-August, the Cloud Files team will make a system change that is designed to allow the Cloud Files infrastructure to scale more efficiently, reduce the risk of CDN downtime and increase the protection of your CDN URLs from DDoS (distributed denial of service) attacks.

In order to do this, we have to change the format of our CDN URLs.

Today, if you add a file to your container (e.g. mydog.png) and CDN-enable it, that CDN URL would have a format that looks like this:

http://c25810.r10.cf1.rackcdn.com/mydog.png

After we complete our change, your new CDN URL would have a format that looks like this:

http://80745c48926cd286a5a0-48261ebe0e4c795a565ece6b9cca2fe8.r10.cf1.rackcdn.com/mydog.png

Once we have made this change, both our control panels and our APIs will return the new form URLs.  While the URL you see will be different from your existing URL, existing URLs will always continue to work as normal. 

This change will take several weeks as we upgrade each of our datacenters, and should be implemented by the end of August for all customers.

If you have any questions about this change and how it will affect your content, please feel free to reach out to me directly, megan.wohlford@rackspace.com[1].

Sincerely,
Your Fanatical Support Team
