Continuing with the work started last week[1], we plan to deploy 1.17
to more wikis in a couple hours.  We had hoped we would be able to
figure out the performance issues in the past week, but unfortunately,
the only practical way we have to see the load problems we witnessed
last week is to put the software into production.  We have put a lot
of instrumentation in place to help us diagnose our load issues.  We
plan to start the upcoming deployment by rolling out to
nl.wikipedia.org, and do some debugging (rolling back if necessary).
If we’re able to diagnose and fix the problems quickly, we then plan
to roll out 1.17 more widely.  If we’re still stumped, we may still
roll out to a few more low-traffic wikis, but leave the high-traffic
sites until we figure this out.

We plan to have more updates and detailed information on the
deployment page on mediawiki.org[2].  Thanks for your patience!
