Whither iceweasel-aurora?

[Tim Allen]

A while ago I set up a Debian Testing system (back when Testing was
'wheezy'), and I followed the instructions at http://mozilla.debian.net/
to obtain and install iceweasel-aurora, and everything's been peachy up
until recently.

As I understand it, a week or two ago, Mozilla did their six-weekly
release cycle, and Nightly is now v27 and Aurora is now v26. However, my
iceweasel-aurora build is still v25 so I went to mozilla.debian.net to
see what (if anything) had changed.

As of right now, if I configure the page to say "I am running Debian
testing (Jessie) and I want to install Iceweasel version aurora", it
instructs me to set up rules for the unstable and experimental
repositories on "cdn.debian.net" (which I understand is just a handy
way to refer to "the geographically nearest Debian mirror"). I already
have unstable and experimental repos set up, but "apt-cache policy
iceweasel" doesn't list any iceweasel packages in experimental.

If I configure the page to say "I am running Debian unstable...", I get
the previous instructions about adding a repo at mozilla.debian.net,
which now gives me 404 errors.

So: have I missed some big announcement about the future of
iceweasel-aurora packages? Have they moved somewhere else I haven't yet
found? Are they pending some packaging work still in-progress? Have they
been dropped due to lack of interest? If there are currently no packages
but there might be in the future, what repositor(y|ies) are they likely
to appear in?
