>From: Unidata User Support <address@hidden> >Organization: Unidata Program Center/UCAR >Keywords: IDD atm.geo.nsf.gov IDD sites feeding from atm.geo.nsf.gov: The top level IDD relay node atm.geo.nsf.gov has been inaccessible since 22:10Z. We are unable to contact any machines at the NSF/ATM offices, so it appears that they took a significant network or power hit. Sites feeding from atm should failover to their alternate feed sites, or, if their alternate feed site gets their data from atm, they should failover to idd.unidata.ucar.edu. We will let you know when atm has returned to service. Friday, argh!! Tom Yoksas
