November 17, 2016 down. 01 December 2016 at 17:00 UTC – all web and anonymous ftp access is restored for access to the archive. NOTE: restoration could occur sooner but no guarantees are made. Currently used addresses, e.g., cddis.nasa.gov or cddis.gsfc.nasa.gov, will continue to work as before the transition. However, if you are using a numeric IP address to access any CDDIS resources your scripts will fail as all current IP addresses will change during the transition. 02 December 2016 – All CDDIS operations should be returned to normal service. While CDDIS is unavailable, users can access one of the other data centers supporting the services: IGS: https://igs.org/data-access/#global-dcs ILRS: http://ilrs.gsfc.nasa.gov/data_and_products/data_centers/index.html (check before November 30!) IVS: http://ivscc.gsfc.nasa.gov/about/org/components/dc-list.html IDS: http://ids-doris.org/data-products/info.html All questions on the CDDIS transition should be directed to cddis-help@lists.nasa.gov.
