FTP will be disallowed on the US GDAC / ARGO in the near future. The exact date is unknown, but it could be as early as this month.
At that point ftp’s to ftp.usgodae.org (for puts) and usgodae.org (for gets) will cease to work.
Folks that have been using ftp to download data from the US GDAC / ARGO should transition to using wget or similar tool that works over https. The wget over https is currently supported.
