We will have a scheduled maintenance window tonight from 6:00pm to 11:00pm PDT. The following changes will take place:

• 9:00pm PDT (0400 UTC) addons.mozilla.org update. We’ll be updating addons.mozilla.org to pick up code updates (bug 523428). Duration 30 minutes.
• 9:00pm PDT (0400 UTC) We’ll be rolling changes to push several production websites out of Amsterdam. This involves changing DNS over to our Zeus GLB servers. No downtime expected.
  The following sites will be moved tonight:
  

  • www.spreadfirefox.com
  • support.mozilla.com (bug 522923)

Please let me know if you have any reason why we should not proceed with this 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.

Feel free to comment directly if you see issues past the planned downtime.
