svn.wikimedia.org will take a short down time tomorrow 9/19 around 3pm
PST (22:00 UTC).
We're going to upgrade our soon to be EOL release of Ubuntu and pick up
some new packages as a result.
The upgrade itself will have us go from 7.04->7.10->8.04 and thus I'm
setting aside a whole hour in case the worse happens.
Please take care to know that commits should be avoided during this time.
I'll mail out again when the upgrade starts and ends along with
mentioning it in wikimedia irc channels.
