We will have a scheduled maintenance window tonight from 7pm to 11:00pm PDT. This is being tracked in master bug 447566.  The following changes will take place:

• 7:00pm PDT (0200 UTC) addons.mozilla.org updates.  We’ll be updating addons.mozilla.org to pick up recent code updates. No downtime is expected.
• 8:00pm PDT (0300 UTC) Wiki and blog upgrades. We’ll be upgrading most wikis and blogs hosted by Mozilla. Duration 3 hours.

Sites impacted:

• wiki.mozilla.org
  (staged at wiki.stage.mozilla.com)
• developer.mozilla.org/devnews/
• developer.mozilla.org/webwatch/
• labs.mozilla.com
• www.firefoxflicks.com/backstage/
• www.firefoxflicks.com/web-diaries/
• blog.lizardwrangler.com

Note that blog.mozilla.com (blogs) and developer.mozilla.org (wikis) will not be impacted by this downtime.

Please let me know if you have any reason why we should not proceed with the planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window.

As mentioned, this maintenance window is tracked in bug 447566. Feel free to comment directly in that bug if you see issues past the planned downtime.
