The Free On-line Dictionary of Computing (30 December 2018):

archive site
FTP archive

    (Or "FTP site", "FTP archive") An Internet host
   where program source, documents, e-mail or news messages are
   stored for public access via anonymous FTP, Gopher,
   web or other document distribution system.  There may
   be several archive sites (mirrors) for, e.g., a Usenet
   newsgroup though one may be recognised as the main one.

   FTP servers were common on the Internet for about ten years but
   have been largely replaced by web servers since the invention of
   the World-Wide Web and its HTTP protocol.

   Some well-known archive sites included Imperial College, UK
   (ftp://src.doc.ic.ac.uk/), UUNET, USA (ftp://ftp.uu.net/), GNU
   archive site.

   The archie service attempted to index the contents of FTP
   archives, foreshadowing the indexing of the web by Google and
   others.
