I am writing to inquire about your
site’s use of FTP and the possibility of migrating over to
Secure FTP in order to comply with our company’s security
compliance requirements.
Does your site offer Secure FTP for your
IANA downloads and if not, what would it take to enable this
protocol so our company could securely download your files?
Currently, we use this URL to download the IANA time zone
files which is not secure: ftp://ftp.iana.org/tz/
