This is a list of all top domains scanned for the report What Large Sites Use
grouped by CDN detected. Feel free to verify the detected CDNs by checking out the CDN detector provided by cdnplanet.com
and report misdetection in the comments.
For each domain the main page was fetched. All <script> and <img> domains where checked for CDNs behind them. Note that this does not necessarily find the primary CDN due to scripting libraries loaded from other CDNs (e.g. jQuery).
Each site might appear multiple times which might hint on a transparent Multi-CDN provider.
Additionally in the case of Cedexis it is not clear if it is used just for monitoring or as Multi-CDN.
