Unidata IDD and ADDE users of idd.cise-nsf.gov/adde.cise-nsf.gov: The Unidata IDD toplevel relay node at the NSF/ATM offices in Northern Virginia (atm.geo.nsf.gov AKA idd.cise-nsf.gov AKE adde.geo.nsf.gov AKA adde.cise-nsf.gov, etc) will be unavailable from 22:00 Eastern time today, Nov. 4 until 12:00 Eastern time tomorrow, Nov. 5 for UPS service. Sites receiving feeds from the IDD relay node and/or ADDE service from the ADDE server should switch to alternate sites for the duration of this outage and then switch back. We apologize for the interruption of service...
