Without adding a version number to the end of a tag, how long does the cache live on the CDN?

If I just directly hit utag.2.js, when can I expect to see the latest version out on the edge of the CDN?

Hi @jrmy. The CDN cache is 5 minutes, so even with no cachebuster, you can expect the file to be updated at the very latest a full 5 minutes after the publish finishes. Craig.
Check out our new Swift integration library for iOS, macOS, tvOS and watchOS: https://github.com/Tealium/tealium-swift with updated
documentation https://community.tealiumiq.com/t5/Swift/tkb-p/swift.

File Time To Live
utag.js / utag.sync.js 5 min
mobile.html (Mobile Webview Component) 7 days
