Announcement of new IERS RS/PC website


The U.S. Naval Observatory's Earth Orientation department is pleased to
announce the re-opening of the official IERS Rapid Service / Prediction
Center website at the following URL address:

https://maia.usno.navy.mil

Starting Feb 10, 2022, this site will be the primary public source for
data products published by the IERS Rapid Service / Prediction Center,
as well as the primary source for announcements and information
concerning those products. Data products may be found through browsing
the site, or downloaded directly from the main product index at
https://maia.usno.navy.mil/ser7/

In addition to the overhauled website design, we have also made our
services more robust and secure:

* We have moved to distributing our products via HTTPS for increased
data integrity and security of data transmission. Please note that the
unsecured HTTP protocol is no longer supported.

* Our website and data are now hosted on an Amazon Web Services Cloud
environment, improving server up-time and reliability.

* We have consolidated our publication servers to a single instance,
removing any confusion over the "best" server to use. The former backup
site (toshi.nofs.navy.mil) has been retired and will not be returning.

* A new version of the EO Matrix Calculator web application with an
improved interface is now available at
https://maia.usno.navy.mil/matrix-calculator

During the outage, we hope you were able to continue receiving our
products through the IERS Data and Information System or through NASA
CDDIS, which graciously provided mirrors for our data while our main
site was down. While this was not ideal for some customers, we thank you
for your patience and understanding while we made several improvements
to our website. All data products will continue to be uploaded to the
IERS mirrors at www.iers.org and ftp.iers.org as well as the CDDIS
mirror at https://cddis.nasa.gov/archive/products/iers/, so users should
not expect any of their current links or data retrieval scripts to
break. However, we encourage users to review their options and begin
transitioning to https://maia.usno.navy.mil as their primary source if
this new site meets their needs, as this site will receive our
publications more promptly and directly, and does not require login to
any user accounts as in the case of NASA CDDIS.
