-If no providers are returned, the issue may lie in the content publishing lifecycle, specifically _reprovider runs_, the continuous process in which a node advertises provider records. _Provider records_ are mappings of CIDs to network addresses, and have an expiration time of 48 hours, which accounts for provider churn. Generally speaking, as more files are added to an IPFS node, the longer reprovide runs take. When a reprovide run takes longer than 24 hours (the expiration time for provider records), CIDs will no longer be discoverable.
