Why Are Certain Files Not Downloadable Even Though They Have Not Expired (365 Days)?
Although their cache time to live (TTL) is 365 days, CDN points of presence (PoPs) regularly delete cached content that has not recently been accessed, regardless of the content's expiration time.
You can prefetch resources so that users can obtain the most recent resources from CDN PoPs upon first access. For details, see Cache Purge and Prefetch.
