All,
The Migration team is in the last lap on completing the remaining tasks to ready our software stack and Ashburn infrastructure for the big switchover day.
Per my last update,http://lists.wikimedia.org/pipermail/wikitech-l/2012-October/063668.html with the Fundraising activity behind us now, the team has scheduled the *week of 22nd January*, 2013 to perform the switchover. We are going to block a 8-hour migration window on the *22nd, 23rd and 24**th*. During those periods, *17:00 UTC to 01:00 UTC hours (9am to 5pm PST*), there will be intermittent blackouts and they will be treated as 'planned' outages. You can follow the migration on irc.freenode.org in the #wikimedia-operations channel.
The team is putting the finishing touches to the last few tasks and we will make the final Go/No decision on 18th Jan, 2013. An update will send out then. For those interested in tracking the progress, the meeting notes are captured on this wikitech pagehttp://wikitech.wikimedia.org/view/Eqiad_Migration_Planning#Improving_Switchover .
*Please note that we will be restricting code deployment during that week, allowing only emergency and critical ones only.*
Thanks.
CT Woo
