Ok is there any way for mirrors to check there status ie why its failing
so they can do something about it...

The "SIZE" command is not standardised. Check RFC 959 for a list
of standard FTP commands.

Most FTP servers provide the size of the upcoming transfer in the
150-response to RETR, and libcurl attempts to figure out the size from
that if the SIZE command didn't work.  You could then abort.
