Wikipedia is moving their Ashburn VA datacenter, 17-01UTC three days in a row, 22/3/4 January. Print this out and hang it on the wall you keep such things on, so everyone will know. Apologies for the crappy line wrap; I've had 36 RFC-compliance bugs open on Zimbra for about 4 years now. Cheers, -- jra ----- Forwarded Message -----

From: "Ct Woo" <ctwoo@wikimedia.org> To: "Wikimedia developers" <wikitech-l@lists.wikimedia.org>, "Development and Operations Engineers" <engineering@lists.wikimedia.org> Sent: Friday, January 11, 2013 3:07:15 PM Subject: [Wikitech-l] Update on Ashburn data center switchover / migration – target date is week of 1/22/13 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 page<http://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.
