 * elasticsearch servers
 * for labs too
 * performance testing?
 * using tampa? we’ve decom’d all the apaches now ;-)
 * use new DC
 * services
 * docs and training for the various APIs

Performance

 * Ori is working on branching Apache request-handling on cookie
 * MaxSem has a patch for porting Wikidiff2 to HHVM
 * Lock contention fixes for User preferences and TMH transcode table
 * WhatLinksHere schema change https://gerrit.wikimedia.org/r/#/c/117373/
 * Anyone want to do https://bugzilla.wikimedia.org/show_bug.cgi?id=57176 ?
 * Antoine working on HHVM integration in labs; Ori will review 
 * Started with Chad to set up an HHVM build node for Jenkins, didn’t finish last week

Bugs we should look at

 * Not a bug filed, but lsearchd is a little wonky.
 * !log entry from earlier: enwiki search indexes don't look happy. sporadic reports of "search request timed out" from users, cpu usage pretty high. possibly unrelated but logs getting spammed with: "Retry, temporal error for query..."

Deployment tooling / RelEng

 * setup quarterly meeting to review post-mortems
 * SWAT team finalization
 * Roan, Matt Walker, Nik, MaxSem, Ori
 * See thread about removing old versions of mw and l10n cache (when)
 * See Gerrit Commit Wars thread on wikitech-l ;)
 * Preferably don’t, unless you’ve got time to read 96 e-mails.

Search

 * Upgrade to 1.0.1 went well
 * Working on budget for more servers
 * Going to simulate more load to look for issues
 * Kicked off design work today

SecurePoll

 * Brad working on HTMLForm
 * Dan and James A to brainstorm requirements for the voter eligibility requirements and workflow

Security

 * Bug 62497 - Review needed (Aaron?)
