We will have a scheduled maintenance window tonight from 7:00pm to 11:00pm PST. The following changes will take place:

• 7:00pm PST (0300 UTC) support.mozilla.com / SUMO updates. We’ll be updating support.mozilla.com to pick up code updates (bug 480342). No downtime expected.
• 7:00pm PST (0300 UTC)  crash-stats.mozilla.com (Socorro) database maintenance & content push. We’ll be replacing a faulty DIMM module (bug 479793) and picking up code updates (bug 480418).  During this time, crash-stats.mozilla.com will be offline. crash-reports.mozilla.com will be up and accept crashes. They will be queued and processed later.  Duration 20 minutes.

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 in those bugs if you see issues past the planned downtime.
