The Standing Offers and Supply Arrangements (SOSA) database is undergoing scheduled maintenance. Due to this maintenance, we are unable to release new SOSA records this week. The current file will contain the same active records that were released in the April 8, 2016 SOSA open data file, and any expired records will be removed. The regular weekly publication of new SOSA records will resume on April 22, 2016. On this date, the SOSA open data file will contain new standing offer and supply arrangement records, with expired records removed.
