I just put up a new post about the TCL announcement that its not far away from offering decent broadband for its cable users. At last for us that means a faster connection for our web servers :)

It looks like ChCh will see the first installations and then later Wellington and Auckland.
I have emailed TCL for more information on dates etc so will keep you updated.
