Latency based selection of fractional-storage servers, including the steps of identifying a first group of fractional-storage servers estimated to have low response latencies in relation to an assembling device. Retrieving, by the assembling device from a second group of fractional-storage servers, enough erasure-coded fragments for reconstructing approximately sequential segments of streaming content. While retrieving the fragments, identifying at least one server from the second group having latency higher than a certain threshold in response to a fragment pull protocol request. And using the fragment pull protocol to replace the identified server with at least one server selected from the first group.
