Is there any problem in the atm.geo.nsf.gov site. There is no problem with atm.geo.nsf.gov currently. Some time ago non-Internet2 connections to the machine were disabled by the system admins at NSF since the volume of data the machine was sending to downstreams would consume NSF's commodity network connection if their Internet2 link failed. I don't believe that I have seen any machine from your site feeding from atm since that change. Are you sure that you have been getting data from atm recently? If your feed requests to atm do, in fact, go over commodity Internet and not Internet2, you will need to feed from some other relay in the IDD. To test if this is the case, please run a traceroute from your LDM machine to atm: <while logged in as 'ldm' on your LDM machine> traceroute atm.geo.nsf.gov and send us the results. In the meantime, and until we can get another top level relay established on the East coast, you can feed from the top level relay node we operate at UCAR, idd.unidata.ucar.edu. >David Yeung >Hong Kong University of Science and Technology Cheers, Tom Yoksas -- NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
