# Mozilla Scheduled Downtime – 03/18/2010, 9pm – 11pm PDT (0400 – 0600 03/19/2010 UTC)

We will have a scheduled maintenance window tonight from 9:00pm to 11:00pm PDT. The following changes will take place:

• 9:30pm PDT (0430 UTC) wiki.mozilla.org & intranet wiki upgrades. We’ll be upgrading the MediaWiki software on these sites. Duration 1 hour.

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.
