As announced on the Drupal.org front page and at http://drupal.org/node/1121304, Drupal.org will be going down for scheduled maintenance for approximately 20 minutes at 11am local time on April 12, 2011. The official announcement is included below.
Please keep in mind that while some things won't work while Drupal.org is undergoing maintenance (such as logging in), you can still interact with Drupal community members in and around Los Angeles here on http://groups.drupal.org/la and in real-time on IRC at #drupal-la.
Why post an event announcement? It's possible that new members to our community may not have gotten the news that this downtime has been scheduled. Unless you're heavily involved with Drupal or the Drupal community (i.e. you go to all the meetups, read Planet Drupal, are on the official Drupal.org mailing lists, etc.) it's possible you may not have heard this was happening.
Additionally, anyone who subscribes to this group's iCal feed at http://groups.drupal.org/ical/3002 will now have the maintenance period show up in their calendar.
Official announcement
Short downtime on Tuesday 2011-04-12, 18:00 UTC
We will be deploying forum2 and this requires the full attention of the database, so we'll take drupal.org down. This should take about 20 minutes. The subdomains will not be affected, but you will not be able to log on during that time.
