Freezing Rails v2.3.5 - dev.rubyonrails.org down?

Hello, we are trying to freeze our rails app to v2.3.5 and we are
running this command:
rake rails:freeze:edge RELEASE=2.3.5

But it is failing trying to download the zip from dev.rubyonrails.org
(which appears to be down):

Downloading Rails from
http://dev.rubyonrails.org/archives/rails_2.3.5.zip
rake aborted!
Connection reset by peer

Is there some way to pass a new host to download the archive or are we
going about this the wrong way? Any help would be appreciated, this is
on a new host on a production environment and we are suffering with the
wrong version of rails.
Thanks so much.

Have you tried the freeze:gems task? that shouldn't have to fetch
anything from the network.
