== Call outs ==
*  QUnit failures with Jenkins (ie https://phabricator.wikimedia.org/T153038
 ) is poping up time-to-time. Some more eyes are needed.
* DBAs asking for more eyes on
http://phabricator.wikimedia.org/T159319 (security
bug) clicking certain links 5 times brings down a 512GB mediawiki database
(either security, performance or mediawiki-core)


=== Technology ===

== Analytics ==
* Blocked on DBA chnages for eventlogging change, we wnat to have user
agent parsed on db but length is over column limit and it gets truncated:
https://phabricator.wikimedia.org/T160454


   - Finished cluster upgrade to new cloudera, no major disruptions to
   existing jobs but we had to modify our most complicated jobs, the edit
   reconstruction



   - Many tweaks to piwik (system we use to count pageviews to things such
   us annual report) so it can sustain usage, we had to ask iOS team to lower
   request count.



   - Prototype for new wikistats 2.0 frontend on the works, using vue.js,
   just storyboard for now, no real data:
