Problem using zsync

[John Kim]

Hello QA Team,

I want to use zsync.  After browsing the web for some more information, I
understood that the iso file must be in the harddrive, namely the home
folder, for zsync to work.  So I placed a recently downloaded quantal image
on my home folder and copy-pasted the command.  But this came out as my
output.

john at thunderbolt:~$ zsync
http://cdimage.ubuntu.com/daily-live/20120819/quantal-desktop-amd64.iso.zsync
cdimage.ubuntu.com: Connection timed out
failed on url
http://cdimage.ubuntu.com/daily-live/20120819/quantal-desktop-amd64.iso.zsync
could not read control file from URL
http://cdimage.ubuntu.com/daily-live/20120819/quantal-desktop-amd64.iso.zsync
john at thunderbolt:~$

It failed to "read control file." What have I done wrong?  How can I make
zsync work? Thanks.
