The Vagrant managed LXC container setup by

need to manually restart their Vagrant containers:
$ ssh my-instance.eqiad.wmflabs
$ cd /srv/mediawiki-vagrant
$ vagrant up
Sorry for the inconvenience. If you have troubles with an instance
that was working before the reboot (or even one that wasn't), come to
#wikimedia-labs for help. Feel free to ping me there (bd808) if you
can't find others available to help. I may not get back to you
immediately but my bouncer will help me find your questions later if
I'm offline for lame things like food and sleep.

Yuvi reminded me of this issue earlier this week. This morning Andrew
merged a change [2] for me that adds an Upstart script that will check
for an existing but stopped MediaWiki-Vagrant LXC container when the
Labs instance boots. If one is found then it will attempt to boot it
using the normal `vagrant up` command. This change should propagate to
all hosts using role::labs::mediawiki_vagrant over the next 20 minutes
or so. If you'd like to make sure that your instances have it, ssh in
and run `sudo puppet agent --test --verbose` to force a Puppet run and
look for the file /etc/init/mediawiki-vagrant.conf afterwards.
Thanks for writing this, Bryan. At the rate that security exploits are
appearing these days, bolstering instances against arbitrary reboots is
something we should all be thinking about.
