Alex and I have spent much of the day hunting down bugs, and the obvious
ones are now fixed. The only issue that I'm still seeing is that if
you're a member of every single project, logins are very slow...
fortunately I am probably the only user bit by this :)
So, now: please open a phab task if you encounter bad behavior on
wikitech, and assign it to me or direct my attention to it via email or IRC.
Many thanks to Alex Monk for all his code review, and thanks to everyone
for your patience with the downtime.

Update:
This migration is complete. There are a bunch of bugs with labs
features in wikitech which I'm now hunting down one by one. In the
meantime, CI should be working again, and most common wikitech actions
should mostly work.
I'll send another 'all clear' once I've stamped out some of the more
obvious bugs. In the meantime maybe hold off on filing phab tickets
since most likely we already know :)

Executive summary:
CI tests won't run for a while tomorrow. Also you won't be able
to log into Wikitech. This will begin at 16:00 UTC (8:00 AM in
California) and may take a couple of hours.
Full story:
As part of a long-overdue tech-debt payment[0], I'll be migrating
all of the Labs project, membership and role data from ldap into
mysql[1]. Keystone (the Labs Openstack authentication layer) will be
shut off briefly, and subsequently will have incomplete data while
things are gradually copied over from Ldap.
At the same time, Alex will be rolling out a bunch of
OpenStackManager patches[2] to cope with the new reality. I've
tested these quite a lot, but no doubt there will be unexpected
issues with such a big refactor.
Existing, running labs and tools sessions should not be
affected. New instance creation will be disabled for part of the
window, which will prevent CI from starting new tests. Wikitech login
will be disabled, and users will have to login afresh after logins
are restored.
There is, unfortunately, no user-facing improvement associated
with this update. If all goes perfectly, Wikitech will be restored
to its original state but be slightly slower. If, after the update,
anyone encounters new Wikitech issues (and I emphasize the NEW),
please open a phab ticket and inform me immediately.
As always, in the worst case scenario you can refer to our doc
site of last resort, https://wikitech-static.wikimedia.org
