This weekend, they are making The Switch. They have started at 18:00 this evening, and I am on call. If something happens that they can't fix (which shouldn't occur, but you never know), they will call me, and maybe I can help them.
I got their migration plan in the mail -- all 21 pages of it. The list of people who are involved in the operation this weekend is about 45 people long, and there are all sorts of 'go/no-go' decisions at every step, and rollback scenario's and crisis-management in the case of a no-go.
According to the plan, I should receive a notification when they're done for the night, but so far I haven't heard anything from them. I even checked whether the phone number in their contact list is the right one, but that checked out OK. I'm not sure which batch of 'standby-people' I'm in, but this could go on until midnight according to their schedule.
I can leave the phone with klik and take that shower anyway, I guess.
Edit: We went to sleep around midnight. Half an hour later I got a status-update via SMS. Some things went OK, some things took more time -- so they are back at it since half an hour now, apparently. No panic calls yet -- but then again the actual users are going to test from 13:00 onwards. There are 10 users scheduled to test our part of it. We'll see.
