Jan, Since the files could be served from any one of our CDNs, checking http://tags.tiqcdn.com/monitor will tell you which CDN send you that file. Which CDN will serve files to the users of your site will depend on the performance of each CDN in each end user’s geographic region. Our multi-CDN (mCDN) platform takes into consideration several aspects of each CDNs performance in every geographic region. Therefore, the CDN that is preforming well right now might not be the same in 10 minutes. The user might get a different CDN on their next visit because of the changing performance of each CDN over time. It is safe to say your end users will be getting the best preforming CDN in their region. Sincerely, Jason Bain Tealium Inc.
