Drupal.org will be affected by maintenance Monday, December 15th 17:00 PST, 01:00 UTC (1 day after).
New database servers are being deployed for Drupal.org. This hardware refresh should greatly improve database query performance on Drupal.org. The deployment should require less than 15 minutes of downtime on Drupal.org if no major issues are encountered.
Please follow the @drupal_infra Twitter account for any issues encountered during the maintenance window.
