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. * * * * Questions and enquiries about EOPs can be emailed to the * * following address: * * usn.ncr.navobsydc.mbx.eopcp@mail.mil * * * * Distribution statement A. * * Approved for public release: distribution unlimited. * * * *********************************************************************** ________________________________________________________________________ The contributed observations used in the preparation of this Bulletin are available at .
