     * Notice of Publication Web and FTP Shutdown:                         *
     * The US Naval Observatory's Rapid Service/Prediction Center web and  *
     * FTP sites (at maia.usno.navy.mil and toshi.nofs.navy.mil) must      *
     * undergo modernization and have been offline since 24 October 2019.  *
     * The expected completion of work and return of service is no earlier *
     * than Autumn of 2020 . Please visit https://www.usno.navy.mil and    *
     * submit a Requirements Form to the USNO Public Affairs Official      *
     * (PAO) if the information you are seeking is not accessible via      *
     * another means.  If the Requirements Form is not available, please   *
     * contact the USNO PAO Geoff Chester at email address directly        *
     * geoff.chester@navy.mil or phone number 202 762 1438.                *
     *                                                                     *
     * Although the Bulletin A makes several references to maia, one       *
     * should note that the paragraph above supercedes any information     *
     * that is contained in the Bulletin A text. Because some users mis-   *
     * takenly use Bulletin A (ser7.dat) instead of other formats (such as *
     * finals2000A.daily) for operational, machine-to-machine uses, we     *
     * do not wish to change the spacing or text of the files.  In the     *
     * past, when spacings had changed, users had stated that any change   *
     * to the Bulletin format outside of this remarks area had broken      *
     * their operations. Therefore, we have not removed the old references *
     * to maia within the text of the Bulletin A (ser7.dat file).          *
     *                                                                     *
     * This shutdown has lead to the indefinite cessation of IERS          *
     * Bulletin A distribution emails. If this occurs, current             *
     * subscribers to the Bulletin A email distribution list may receive   *
     * future mailings from a different address (if this service is        *
     * restored). In the meantime, we will be unable to process email      *
     * subscription/unsubscription requests.                               *
