Sorry, dtube hosts it from the cut they take, 1 month per 4.4 cent and gigabyte, currently my IPFS node isnt running consistently as it is my only PC so this will happen from time to time, however, i phoned a friend who probably has some old PC left over which i will when i have it add a bigger Harddrive to and use as consistently running IPFS node. New to the whole system of IPFS and Steem myself.
