From the Bureau of Labor Statistics:
The Bureau of Labor Statistics will be ending its support of Anonymous FTP Service effective March 2014. The BLS FTP site ftp://ftp.bls.gov/ will be replaced by a HTTP site called http://download.bls.gov/. The new HTTP site will host identical downloadable files as those available on the FTP site except for files located in the special.request directory. Please visit the program homepages at www.bls.gov for specifics on the availability of special request files. To ensure a smooth transition, BLS FTP users are strongly recommended to update any automated scripts and begin using the new HTTP site as soon as possible.
Note: The FTP site (ftp://ftp.bls.gov) will be shut down on February 28, 2014.
