For security reasons, links to IERS data at datacenter.iers.org had to be changed. You will not note this change when accessing IERS data through https://www.iers.org/products or https://datacenter.iers.org, because all links have been updated. Also data at ftp.iers.org are not concerned. Only when you will use a link to an individual file (e.g., the link to the latest version of Bulletin A) saved in your browser or elsewhere or when you will find an old link by searching the Internet, there will be an error message from the server. In this case, please go to one of the sites given above to find out the new URL.
