Sorry, I forgot to address the patch tracker.  I wrote some hours ago:

An update:

The attached patch for berlin serves more but not all URLs
properly when testing on a VM.

I found one problem; the nginx locations for redirecting old URLs can
be given a higher priority via specifying = before the location path.

I am sorry for neglecting this for so long until
Christopher Baines offered to help a few days ago.  Now I too started
investigating myself again.

I cleared the browser cache, restarted nscd and tested these URLs
(with a changed /etc/hosts file pointing guix.gnu.org to the VM):

Still failing:

http://guix.gnu.org/graphics

http://guix.gnu.org/blog/2013/back-from-the-european-lisp-symposium

worked before wip-i18n but stopped working.  Hrm.

These seem to fail but I could not properly build the manual yet:

http://guix.gnu.org/manual/en/html_node/Miscellaneous-Services.html

http://guix.gnu.org/manual/html_node/Power-management-Services.html


The rest looks good:

http://guix.gnu.org/news/timely-delivery-of-security-updates.html

http://guix.gnu.org/security/

http://guix.gnu.org/blog/2016/back-from-the-gnu-hackers-meeting-2016/

http://guix.gnu.org/en/blog/2017/back-from-fosdem-2017

http://guix.gnu.org/de/blog/2016/back-from-gbcuw-2016/

works.

http://guix.gnu.org/news/coming-events

http://guix.gnu.org/news

never worked, so it’s OK that these URLs don’t work.

http://guix.gnu.org/news/

This redirect now works but did not work before wip-i18n (??).


I will continue to investigate.

Regards,
Florian
