CDDIS successfully moved all primary operations to an upgraded computer system on December 01, 2016; in total, the CDDIS archive was inaccessible to the user community for approximately 30 hours during the transition. The new IT infrastructure provides a more robust, reliable, and expandable system with increased storage capacity to handle future growth. All suppliers of data, derived products, and ancillary files for the CDDIS archive were required to modify their software to use the HTTP protocol for file upload. In addition to new hardware, the CDDIS archive processing software was redesigned and improved to provide for more efficient operations and additional QC on incoming files.
On November 30, 2016 at 13:00 UTC, CDDIS will terminate all services (ftp, CDDIS/ILRS/SGP websites, data deliveries) as we transition to all new hardware and facilities. We are projecting about 24 hours to fully move to our new facilities and ensure all operations are back to normal. As such, all users need to plan on a 24+ hour disruption of service to the CDDIS archive with resumption of normal operations no earlier than December 01, 2016 at 17:00 UTC.
In summary the following will take place:
- 30 November 2016 at 13:00 UTC – All current production services (ftp, http, etc) will be shutdown.
- 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: http://www.igs.org/about/data-centers
- 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
Beginning this week, NASA will be conducting a survey for users of NASA Earth science data and services, which includes the Crustal Dynamics Data Information System (CDDIS). The CDDIS is one of twelve NASA Earth Observing System Data and Information System (EOSDIS) science data centers evaluated by this survey. The purpose of this survey is to help NASA and the DAACs assess customer satisfaction and improve future services. Suggestions from past surveys have been implemented to improve the tools and services offered by the CDDIS.
The American Customer Satisfaction Index (ACSI) is the only national cross-industry measure of customer satisfaction in the United States. NASA commissioned the CFI Group, an independent research and consulting organization to conduct the survey. Presentations of these results given to NASA Earth science are available at: http://earthdata.nasa.gov/about-eosdis/performance/american-customer-satisfaction-index-reports.
Please participate! Your feedback affects our future performance and helps to identify science needs. You will be able to take the survey for each DAAC you use. If you use NASA Earth science data and services and would like to take the survey but did not receive an e-mail with the survey link, please contact email@example.com. This is your opportunity to influence the priorities of the DAACs. Thank you in advance to all of you who are willing to spend a few minutes to complete the survey.
