     * 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. The latest IERS Bulletin A   *
     * can be accessed at https://maia.usno.navy.mil/ser7/ser7.dat         *
     *                                                                     *
     * 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 unsecured plain HTTP is no longer supported.   *
     *   - The 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 NASA CDDIS, which graciously provided a        *
     * mirror 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 CDDIS mirrors at https://cddis.nasa.gov/archive/products/iers/  *
     * and ftps://gdc.cddis.eosdis.nasa.gov/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 it meets their needs, as it will         *
     * receive our publications more promptly and directly, without        *
     * any need to login to the NASA Earthdata system.                     *
     * Updated EOPs may also be available at IERS:                         *
     *   https://datacenter.iers.org/eop.php                               *
     * EOP data files are uploaded directly from USNO to this site each    *
     * day. For further information, contact the IERS directly.            *
