Mozilla Scheduled Downtime - 9/21/2006, 7pm - 10pm PDT (0200 - 0500 UTC)

We will have a scheduled downtime window this coming Thursday from 7pm to 10pm PDT. The following changes will take place:

* 7pm PDT - Database migrations. We have 2 new database servers to help reduce some of the load. Databases to migrate are: addons, devmowiki, firefoxflicks, labs, quality_wiki, reporter, userpanel and survey. Applications may be down or in a read-only state for the duration of the window.
* 8pm PDT - cm-vpn01 network change. cm-vpn01 will need to be rebooted for a network change. 15 min of downtime is expected.

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. Feel free to email infra@mozilla.org if you see issues past the planned downtime.
