Great GRIB App - GFS models not updated fast enough

Best GRIB viewer I have used. However I am now noticing GFS forecast is not updating often enough. It is 11AM EDT and forecast is 0200. Should be 0800. Have been seeing this delay regularly. Please update every 6 hours when new model is issued. Time matters when going offshore up the coast. Thank you
