+## Hot Retrieval from IPFS
 
-[Saturn](https://saturn.tech/) is a Web3 CDN within Filecoin’s retrieval market that serves data stored on Filecoin with low latency and at a low cost. It consists of independent retrieval providers dedicated to efficient, fast, and reliable data retrieval operations.
+Since most Filecoin nodes are also IPFS nodes, standard practice has been for Filecoin storage providers to also make available a hot copy of any given stored file through IPFS.  Since the algorithm that generates a content address (CID) is the same for both Filecoin and IPFS, the client can request the CID of a file they stored on Filecoin and retrieve it from IPFS, if there is an IPFS node that is able and willing to serve the file.
