src snapshot archives?

In the past I have pulled an initial src tree from
ftp://ftp.netbsd.org/pub/NetBSD-daily/
but today I've found...
ftp://ftp.netbsd.org/pub/NetBSD-daily/LOOK_ELSEWHERE
which explains to go to the new url:
http://nyftp.netbsd.org/pub/NetBSD-daily
but since the protocol changed to http,
it's a lot harder to script a CVS bootstrap

TAG=netbsd-5
daily="http://nyftp.netbsd.org/pub/NetBSD-daily"
last () { # Return the dated path of the last $TAG tgz
        echo "ls -rx" \
        | ftp -4 $daily/$TAG/ \
        | awk '{print $1}'
        }

(only works with ftp protocol)
and even when I get the timestamp, I can't get the source:
Requesting http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-5/200908250000Z/source/sets/src.tgz
ftp: Error retrieving file `500 Internal Error'

What's wrong with the new server?
Any chance we can get the ftp protocol back?
