== tl;dr ==
On June 29th git.wikimedia.org (running Gitblit) will redirect all
requests to Phabricator. The vast majority of requests will be correctly
redirected.
== What is happening? ==
In an effort to reduce the maintenance burden of redudant services we
will be removing git.wikimedia.org. The software that has been serving
git.wikimedia.org, Gitblit, has given our Operations team many headaches
over the years[0] and now that we have all repositories hosted in
Phabricator[1] there is no reason to keep Gitblit around. Phabricator's
Diffusion (the name of the code browser) provides the needed
functionality that Gitblit served (mostly viewing/browsing repositories,
something which Gerrit does not do).
== When will it happen? ==
June 29th
https://wikitech.wikimedia.org/wiki/Deployments#deploycal-item-20160629T1600
== How could this affect me? ==
Potentially, you use an unpopular (in the sense of not used often)
feature of Gitblit that is not supported in Diffusion. This should be
unlikely.
Potentially, a link you follow that pointed to somewhere on
git.wikimedia.org will not redirect correctly. This is also unlikely as
we (mostly @Danny_B and @Paladox) took great care to update many
mediawiki.org templates along with providing very robust redirect
rules[2]. If you find one that isn't working, please let us know (along
with the original url and, if possible, the desired target in
Diffusion).
One known issue to call out: Diffusion does not list commits by person.
However Differential (the code-review tool) does this (not just for new
commits). There is no easy/maintainable way to redirect those,
unfortunately.
Something else broken? Please file a task in Phabricator in the
#Diffusion project[3].
Thanks,
Greg, on behalf of WMF Release Engineering (and all the volunteers who
helped along the way (and Ops!))

== What is happening? ==
Secure connections to RCStream[1] currently use an SSL/TLS certificate[2]
specific to stream.wikimedia.org. To streamline certificate management, we
are moving RCStream behind our misc caching cluster, which will allow us to
use the wildcard certificate[3] for *.wikimedia.org, making the
RCStream-specific certificate redundant. This will reduce operating costs
and improve performance in certain cases.
== When will this happen? ==
June 23rd.
== How could this affect me? ==
This change requires updating the DNS record for stream.wikimedia.org. We
do not expect any service disruptions. It is conceivable (but unlikely)
that you will need to restart your client. If your client is based on one
of the published examples[4], you should be fine. If you are not sure, feel
free to get in touch with me (ori(a)wikimedia.org).
If you are connecting to RCStream over an insecure (http) connection, now
would be a great time to migrate to https. http access to RCStream will
eventually be disabled; migrating now will protect you from any
interruptions down the line. In most cases, making your client use https is
as simple as prefixing 'stream.wikimedia.org' with 'https://'. Sample
client code on Wikitech[4] has been updated.

Hi all,
the Reading Infrastructure team will try to enable AuthManager [1] in WMF
production this week, with the following schedule:
- group0 Tuesday 22:00 UTC (yes, that's pretty much now)
- group1 Wednesday 22:00 UTC
- group2 Thursday 22:00 UTC
I apologize for the very late notice. I realize that such a change should
ideally be fixed long before, advertised via the Tech news etc, but
omitting that seemed like the lesser of two evils. We believe we need to
get AuthManager into the 1.27 release as having to support two completely
different authentication systems in the LTS release would be an
unreasonable burden and risk; to do that, we need to test it in production
in very short order, otherwise the release will be delayed a lot due to
vacations and Wikimania; and we weren't sure until very recently whether we
are able to keep to this schedule.
If all goes well, switching AuthManager on should have very little visible
effect (see earlier announcements [2][3]), but with a change of this
complexity all rarely goes well. If you see authentication-related
problems, please ping or cc Brad Jorsch (IRC: anomie) and me (IRC: tgr). If
we are not around and things break badly, you can revert by setting
wgDisableAuthManager to true in wmf-config.

Hello,
The Discovery Portal team would like to add Wikipedia app
<https://www.mediawiki.org/wiki/Wikimedia_Apps> download badges near the
bottom of the wikipedia.org <https://www.wikipedia.org> portal page and
we're looking for your feedback.
These new app badges will link to a free download of the Wikipedia app for
Android and iOS mobile platforms and will be displayed just to those
visitors to the wikipedia.org portal page that are using a mobile device.
We hope that the app badges will provide an introduction to our visitors
who are interested in, or might prefer to use, the platform-native mobile
apps. It's an update that makes sense to the Portal team, but we wanted to
ask the community for feedback and suggestions.
If you're interested in finding out more, please visit this page
<https://www.mediawiki.org/wiki/Wikipedia.org_add_mobile_app_badges> to
read more details and view the draft mocks. Constructive feedback, thoughts
and ideas can be added and discussed on the talk page
<https://www.mediawiki.org/wiki/Talk:Wikipedia.org_add_mobile_app_badges>;
and additional information about the portal can be found here
<https://www.mediawiki.org/wiki/Wikipedia.org_Portal>.
Cheers,
Deb
