Hi, Are you accessing the data through a regular web browser? What URL are you trying to access? Our data server is still available. Here is the URL for the NCEP GFS Global 0.5 degree catalog page: http://motherlode.ucar.edu:8080/thredds/idd/model/GFS/Global_0p5deg/catalog.html Also, here is the URL for all the data on the server: http://motherlode.ucar.edu:8080/thredds/catalog.html Our archive is only for the last seven days. So, if you are looking at a link to a particular dataset, that dataset may have aged off the archive by now. Hope that helps. Let us know if you have any further questions.
