When the application is deployed across various web servers, incase of CDN failure to service the utag.js files, then, is there a provision in Tealium to fallback to a custom URL to locate utag.js locally in a server?

Hi Venkatachalapathy, Our multi-cdn architecture should take care of this for you. It's been designed so that there is no single point of failure, and there should never be a case where the utag.js is not served, and hence no need to publish to any additional locations. The service monitors from multiple locations around the world and will always serve from the quickest (available) CDN in the visitor's region. If you really wanted to build in extra redundancy (which in my personal opinion is unnecessary), you could host the utag.js file yourself, but you would have to write some custom javascript code on your website to fall back on the self-hosted js file. Hope this helps, but please let me know if anything is unclear. Craig.

Hi Venkat, also note that if you do want to host the files locally instead of using our multi-CDN (or to be used in conjunction with the custom JavaScript code Craig mentioned), you can download the distro files you would need to do so from within the Tealium UI. Note though that each time someone within your organization updates the profile, you will also have to update these locally hosted files manually.
