In 30 minutes the main mail server migration will begin; your email inboxes (if you have them :)) will be inaccessible for around an hour as I confirm the migration was successful & get the processes running.

Mail sent to wikimedia and wikiconferences addresses during this time will be recieved, but not processed. They will be processed once I have confirmed the validity of the migration.

Mailing lists (not this one; the board, office and conference, etc.) will be inaccessible for about 2-3 hours depending on how quickly I can confirm this stage of the migration/
