A method, computer program product, and system includes a processor(s) connecting a first computer system to a boot swarm, initiating formation of a peer to peer network. The processor(s) receive a request from a second computer system, a request for a file. The processor(s) configure the second computer system, including implementing a client application hosted from a resource in the first computer system, to facilitate the second computer system joining the peer to peer network. The processor(s) determine immediate peer(s) in the peer to peer network available to provide the file to the second computer system. The processor(s) generate a magnet link that includes a listing of address(es) of the immediate peer(s), ranking address(es) from best source to worst source for downloading the file. The processor(s) provide the second computer system with the magnet link to utilize in downloading the file from a peer.
